TNT

Description
The TNT (unofficially called the C4 due to its appearance) is a high damage weapon and is the only way to open the bank vault besides using the Kagami Samurai 650. Only one can be placed in the world at a time by a player; leaving the game will keep the TNT in place but it can no longer be detonated remotely, and it must be shot to destroy it.

It can be used on the road or in hallways to create traps, on cars to create mobile bombs, and even on players to collect bounties or to get them to do what you want. It can also be used to destroy cars, kill large swathes of players, ragdoll campers, break windows, destroy ATMs, or to launch people off buildings. Charging at a player with TNT is a common strategy since the game lacks melee weapons and the TNT explosion will likely kill the targeted player in the process.

The player can carry a total of 7, but an eighth can be placed in the world and detonated after refilling the weapon in the gun shop. Thus, it is one of the most useful and versatile early-game weapons.

Enforcers/Mercenaries
One popular method is to place a TNT near the door of the Gem Store. This will instantly kill anyone who exits through the door when detonated at the correct time, and will ragdoll players who just fell. Care must be taken not to detonate it before the players get up because this will not stack the ragdoll duration. Additionally, it can be used to ragdoll players within the Bank Vault to make them easier targets for a high-DPS weapon like the AKM.

TNT takes several hits to destroy the higher-end vehicle/armor combinations so car-bombing is recommended for players that want to kill their enemies easier. TNT burst damage and ragdolling makes it useful for other situations than trapping or raw offense; it can be planted onto other Enforcers so that they can charge into battle and be blown up before they die. As long as the TNT is not attacked to kill the other Enforcer, they will not die from the explosion. However, this leaves them open to attacks in their ragdolled state.

It can also be used to kill through the glass windows at the Treasury room in a much faster and safer way than the old bug involving firing a rifle through the windows, as well as to kill players hiding on ledges. Walls will not protect you or your target, so be careful and keep your distance.

The best way of using TNT for value is socially engineering other players by planting it on them and having them rob something. This can be interrupted by other players attacking your target but always has a massive, guaranteed payout.

Mafia/Mercenaries
One way for Mafia to benefit from TNT is by placing it inside the bank vault. This makes it easier to get a guaranteed kill on players that attempt to kill them, but is nearly worthless if they are camping in the vault to escape from Enforcers, as it resets their bounty to the full 180 seconds. Another way is to place TNT in hidden places in the enforcer's path, such as around the pillar in the Gem Shop. A final way to benefit from TNT is using it to attack high-level players directly. It can be blown up and damage the player if they are trying to run you over. This also knocks them out of their car, allowing you to finish them off.

Counter-strategy
One counter-strategy with TNT is to avoid it. If it is placed in a key location or an area without a significant amount of space this can be very difficult, if not impossible. Killing the person who will detonate the TNT will usually prevent them from getting the full damage from the kill, and they will likely detonate it early rather than follow you and waste time. Alternate routes are possible, but if your enemy has a sniper rifle or is accurate at long range it can result in your death.

Having a teammate shoot the TNT early is the most foolproof way to avoid it, so bring a friend along and take turns sacrificing your lives.

If you have your own TNT or vehicle, using it against the TNT will not work at all. It will only waste it. The best way of using them in this case is to defend those same locations from the other team in the converse way once you have a teammate detonate it. TNT is $1,200 each and players can only have 7 on their person, so making the player rush to the gun shop is an equally valid strategy and but is significantly less sustainable long-term.

Trivia
The TNT cannot be removed or retrieved after being placed. It has no collision and will fall through the world and disappear if the object it is placed on despawns. However, as long as it is attached to a player that does not leave the game, it can persist indefinitely, even through deaths and resets.

TNT can be shot at to detonate it but, curiously, it cannot be detonated through explosions of vehicles or other TNT. It has slightly more HP than a player overall, and if a player shoots at it, then that player gets any resulting kills or damage from the TNT. It also takes penetration multipliers, so weapons that can easily destroy armored vehicles can take out TNT in less hits.

A bug can sometimes occur with players who respawn while TNT is exploding that gives them a 2-star $6,000 bounty.

TNT planted on a player only be removed by falling into the void, whether by climbing the walls on the edge of the map or through exploiting. Fully refilling TNT costs $9,000.
