CS:GO Nuke [Map Guide & Callouts]

#1 guide about Nuke: find the best tactics, nades, smokes and callouts locations. This small but mighty CS map has lots to learn + map cheat sheet!

About Nuke

The original map was an abandoned facility guarding a nuclear missile where the security was breached by terrorists. It had reused the desert textures and sky from Half-Life but when it was added to Counter-Strike: Source, the desert theme and textures were replaced with concrete. It received multiple other changes for CS Source including a larger outside area and the building was also turned into a nuclear power plant.

CSGO Nuke Outside

Once it was added to CSGO, the first version here had some minor changes to the looks and the gameplay. During the Beta, a pro player called Salvatore "Volcano" Garozzo created his version of the map and called it "de_nuke_ve". During the December update, Valve added the changes made in their version of the map as well. The March 2015 update saw Nuke be removed and replaced with Train for some time before it was re-added during Operation Wildfire.The map received another revamp with some major changes. Valve removed one of the vents between the two bombsites and re-opened access tunnels to Lower B which was removed earlier in CSGO history. They also moved Toxic to the side of a ramp, blocked access to an area of Upper A, added easier access to Silo, and tweaked the CT Catwalk slightly too.

Nuke Callouts

Nuke is one of the smallest maps in CSGO and it's unique due to the map being set around a building. It does go inside and the cramped conditions mean close-ranged weapons are prioritized on this map while snipers are a rare sight here.Both Bombsites are inside enclosed buildings and there is a Vent system that runs most of the map providing a connection pathway between the two Bombsites along with Secret. This is also a map that doesn't include a designated Mid area due to the size and layout. However, the entire outdoor area is known as Outside and is where most fighting will take place.

CSGO Nuke Callouts

Despite being a small map, Nuke has a lot of items and places that can be used as cover including the entire Outside area.There is also a Ladder that allows access to the Lobby Roof which is also known as the T Roof due to its position being close to the T Spawn. From the T Roof, it's possible to get onto the Silo which then gives wide oversight over the Outside area. Diagonally opposite the Silo is another roof spot which is closer to the CT Spawn side, there is a ladder in Hell that provides access to a raised area called Heaven.The spawns are on opposite sides of the map to the other and are in small corridors with immediate access to the Outside area and the main building. While there is no direct line of sight from each spawn, teams can very quickly end up in confrontations on this map.If you want to get a better look at other CSGO Map Callouts:

Bombsite A

Site A is inside the main building on the map and the center of a large room. The middle of the site itself has some cover that players can plant the bomb behind. While Site A is part of the largest building, the room itself is connected to some other smaller rooms with doors to the outside.

CSGO Nuke Bombsite A

The top end of Site A also has some Rafters that connects to Heaven allowing a Defender on Heaven to peek inside when needed. There is also the Locker Room next door that has a window allowing someone to look at part of the Outside area, the Garage, and CT Red container.

CSGO Nuke Bombsite A

Bombsite A is also connected to the Lobby via the Hut where a Ladder allows access to the T Roof and also the Silo. It also connects to the Radio Room and the Control room that leads to the Ramp going towards Bombsite B.

How to defend this hotspot

It's common for Terrorists to attack Site A from the Lobby side of the building which means they will enter the room via Squeaky which is a long narrow room.One Defender can be placed at the Tetris area next to Hut though this leaves them exposed from the Main entrance that leads Outside. Instead, there's a box next to the Main door which a player can hide behind and also peak into Squeaky from as well. Some pushes come from Squeaky though most seem to come from the Hut which are very close together. Throwing a flashbang through Squeaky is a great idea, if aimed correctly then it can also flash any Attackers near the Squeaky room in the Lobby.

CSGO Nuke Bombsite A

For the Hut, a player on Rafters can watch that area and can rotate around the area using the barrels on Site A for cover also. While some times like to use two players on Site A, the size of the room makes it possible for Attackers to quickly wipe them both with well-aimed grenades or with the aid of smokes. One player can rotate the entire space and protect it without needing someone else on the site as well.Most defending work will be completed outside where most of the fighting will take place regardless. Despite this, it can still be a good idea to have a player on Heaven to watch over the B Site Ramp and so they can also quickly peek inside and help when Terrorists start to attack in earnest.

How to attack Bombsite A

Smoke grenades are useful for this map and covering Site A with them makes it harder for a Counter-Terrorist to take you by surprise if they're on the Rafters. Entering the room can be tricky but using smokes and flashbangs can make it much easier. Coming from the Main area might be tricky depending on how the Counter-Terrorists are defending the Outside area. Having a player on the Silo would provide some cover for a player to run in through that entrance, however.

CSGO Nuke Bombsite A

It's advisable to always check behind the box next to the Main door as a play might hide behind there for a surprise attack. However, as long as there is an Attacker on Silo the team inside will always have a warning if Defenders try to flank the team and the Silo player could kill them before they can enter the room. Having a player on Silo could also mean that planting the bomb on the Main side helps to keep it safe as it limits access to the room since Defenders would need to use the Heaven access point instead.While not usually a cause for concern, the Vent in the room does link to Site B. This means that any defender at Site B or in the Vents could suddenly appear from that position and throw in a Molotov or grenade. It's a good idea to have a player watching the Vents once the team has control of the space to prevent a grenade wiping out the team.

T Spawn

On the left side of the map is where the Terrorists spawn. It's in a long corridor with different cubby holes and some potential cover as well.

CSGO Nuke T Spawn Callout

The T Spawn is close to Bombsite A and players also have the chance to rush towards the Garage where Secret can be found. For this, however, another Attacker should rush for the T Roof and Silo by climbing the ladder at the Lobby.

CSGO Nuke T Spawn Callout

Attackers can quickly reach Site A via the Lobby and Main doors. For Site B however, they need to g through the Lobby and through to Control which leads to the Ramp area outside. It's also possible to use Secret outside for another path into Site B.

CT Spawn

On Nuke, both teams spawn in similar locations. The CT Spawn is on the opposite side of the map to the T Spawn however, the positioning is essentially the same.

CSGO Nuke CT Spawn Callout

There is less cover in the CT Spawn area but there is a Box just outside. The CT Spawn faces the Heaven and Hell side of the building allowing Defenders quick access to Heaven and the inside of Site A via the Rafters. There is also the Lockers room that connects to Hell and a door into the Site A room.

CSGO Nuke CT Spawn

The spawn is also close to the Garage allowing players to rush there to protect secret or to kill a player on Silo. The closeness to Secret also means easy access to Site B through that entrance however, the CT team can also quickly reach the Ramp. Hell has a door leading to the Ramp area which means the Defenders can get to that area first as well.

Bombsite B

The second Bombsite of the map can be found down the Ramp which is on the opposite side of the map to the Main entrance to Site A. The Ramp has various hiding positions around it which Defenders can use to keep Attackers at bay. This includes the Big Box, a Boost spot, a Stack of boxes, and also a Headshot spot behind the Ramp.Once down the Ramp, it leads onto the Bottom Ramp area with some cover at the end so those coming down aren't immediately killed by any player on the site. There is another potential entrance to Site B via Secret which is a staircase that leads from Outside down into the Tunnels of Site B. The other entrance/exit for Secret is on the opposite side of the map behind the Garage and is something both teams want to protect.

CSGO Nuke Bombsite B

B Site itself is set in a large empty room with very little cover. From the Tunnels, there are double Doors that lead into the room and further along, there is also a smashable Window. The first left inside Secret also leads to the Back Vents where the Vent leads out onto and also the Decon room with a single door connecting to B Site. Bombsite B is currently available in CS:GO wingman 2v2 Mode.

How to defend Bombsite B on Nuke

The Bombsite B double Doors only open when a player is within the range which is something that Defenders can use to their advantage. A Defender can rush to the Secret entrance behind Garage and hide in the Back Vents or in the cubby hole behind the Doors to kill any Attackers who try to use Secret to enter Site B. If no one does but the Attackers are on Site B anyway, the defender can throw a flashbang onto the site by opening the doors and quickly kill the enemies there. Using a surprise attack is also good for making the enemies leave the site for a few seconds to delay them.

CSGO Nuke Bombsite B

Most defending work will be done Outside around the Ramp instead of inside.Using the Boost point allows a player to have a better view of the area and peak over the wall to see if Attackers are coming from Control. Another player could also be set-up at the Headshot point to grab a quick kill or they could be using the Big Box instead. It can be good to have two players here but this area usually only needs one player if another defender is on Heaven. The player at the Boost point could throw a Molotov, smoke, or flashbang towards Control when they hear the Attackers push, it delays them and should allow for a quick kill or two.Inside B Site, however, the space is limited for cover but there is a good hiding spot on the site. Next to the Window is a small cubby hole known as Dark due to it being extremely dark and often requiring a closer check unless players know the map well. Dark allows a player to hide there if desired and makes it easy to throw a Molotov at the entrance to delay Attackers approaching then run through the pre-smashed Window to reposition somewhere else. Alternatively, grenades are also very useful on this map due to the close quarters and are perfect for either killing Attackers on Site B or forcing them to retreat.

How to attack Bombsite B

There are different strategies for Attacking Site B but having a player on the Silo is beneficial regardless of strategy.It can allow them to provide cover for a player trying to rush to Secret so they can get access to the Tunnels. Having a player on Silo also provides your team with needed information about where the Defenders are.

CSGO Nuke Bombsite B

For attacking Site A, there are many different potential strategies including rushing the site with smoke grenades. However, the area Outside of the entrance to the Ramp also needs to be dealt with. It's a good idea to expect there to be at least one player guarding the area though they could be rotating a lot. So, using a flashbang here can be useful and a generic one can be thrown towards the left side of the Ramp to catch most positions there with it. Always be sure to check the Boost spot however and next to the Big Box as well. A player at Headshot would be the most tricky one to catch with a flashbang so at least one Attacker should be dedicated to spotting and killing a player there. There are different ways to deal with the Outside area as well but Terrorists must always be aware of potentially being flanked.


While most of the map is set outside, the main area known as Outside is the front of the building where the Garage area is. The entire outdoors area can be called this so players normally need to expand on it a bit further to say what they're close to or what their callout means.

CSGO Nuke Outside

Outside is incredibly important on this map and it's common for most fighting to take place Outside of the building due to the cramped conditions inside. While fighting is expected here, Outside is also vital for movement and travel across the map. Having players positioned in different places such as on the Silo and Heaven gives some control over the Outside are which is necessary for restricting the other teams' movement.

CSGO Nuke Outside

If one team loses control of Outside then they will be at a serious disadvantage which will most likely cost the game.


Using the Vents provides a quick path between Site A and Site B. This can be very useful for the Defending team as it means players can quickly rush to support whatever site is being attacked.

CSGO Vents Nuke

Similarly, Attackers could use them to their advantage for surprise attacks such as using Secret to reach the Vents then coming back through it towards Site A. The Vents do allow for different strategies and forces both teams to be mindful of them.

Like with most places called Heaven in CSGO, this one is positioned on top of Hell where the ladder doing up to it is.

Heaven Nuke CSGO

Heaven overlooks a lot of the Outside area including where Secret is so Counter-Terrorists can keep an eye on that entrance. The Rafters from Site A also lead up to Heaven which means players can rotate the entire area freely.

Heaven Nuke CSGO

Heaven provides an important route into Site A while also giving Defenders the chance to protect Garage and Secret. Having this information allows the team to prepare and rotate better since teams should then have a better idea of where attacks will come from.

Best Nades, Smokes, and Molotovs

While smoke grenades are important on this map, grenades, in general, are very useful inside the buildings. Nuke is a small map with limited space in the rooms which does mean different strategies can be used here. Some Defenders like to throw Molotov into the Hut on Site A to delay Attackers and others would rather use a grenade.The size of the map and the rooms allow players to explore different techniques and methods with all the throwables in the game.

CSGO Nuke Smokes

All of them can work very well here. It's more a matter of personal taste and ranking for players to decide what else they want to bring into the game other than smoke grenades. Smokes can also be very useful for running across the Outside areas to stop headshots from the enemy team. Different trick shots can be made with throwables to surprise the other team.Nuke is a classic CS: GO map and it's easy to see why Valve decided to not expand the map size or change the layouts too much. It's different to the other maps in the game making Nuke unique in Counter-Strike: Global Offensive. The small size, tight layout, and sneaky Secret area encourage players to do things they don't usually need to do on other maps. Nuke allows for a variety of playstyles to create a fast game with constantly changing tactics and the ability to use any throwable weapon in the game.
