C-4 is a utility slot explosive available to all non-MAX infantry classes, except the Infiltrator. It is unlocked and upgraded using Certification Points.

When equipped, the player holds the C-4's detonator, rather than the bricks themselves. When thrown, C-4 bricks travel a short distance in front of the player and stick to the first non-infantry surface contacted, able to stick to vehicles and deployables. C-4 bricks can be detonated at any time, exploding to deal massive damage in a small area around them.

Players can place up to two bricks of C-4 at a time, increased up to a maximum of four bricks if the Demolitions Pouch suit slot enhancement is in use. If the player respawns after placing any bricks, all placed bricks will despawn peacefully. Accepting a revive will not remove placed C-4.

C-4 can be disarmed using the Nano-Armor Kit, removing it from the world without detonating the explosive. C-4 is also vulnerable to most types of damage, as well as EMP Grenades, all of which will detonate the explosive.

To use C-4, use Aim key (Right Mouse Button by default) to throw a brick, and then Fire key (Left Mouse Button by default) to detonate it. Pressing the button, after small delay, will detonate all C-4 that you have deployed.

After in-game testing, it seems like C-4 bricks have 800 health points (tested with small-arms).[Notes 1]

History[]

October 5, 2022 Update (The Lost Fleet)


May 26, 2021 Hotfix

February 9, 2021 Update (Outfit Wars Returns)

  • C4 Detonator has received a slight update.
  • C4 bricks have received updated visuals.

    • Throwing and triggering C-4 is now more smooth and responsive. With the added control, we’ve also reduced its damage output against most vehicles. Two bricks of C-4 placed on a Main Battle Tank will still destroy it, but a single brick will no longer take 80% of an MBT’s life landing nearby.

  • Fixed a bug causing the first C4 explosion of a gaming session to not play any audio

  • Placed C-4 now has a visible light attached, similar to placed personal mines.

Game Update Number 10 (2022-06-05)

  • Players in the rumble seat of the Harasser should no longer be able to hit the vehicle when firing with the exceptions of the repair tool and physics based projectiles (C-4, grenades, etc)

Game Update Number 4 (2022-03-13)

  • Placed C4 will now despawn when the source player dies

Game Update Number 2 (2022-02-02)

  • Purchasing the second Medic C4 cert will no longer grant every class the ability to carry an additional C4. This bug allowed a number of classes to carry more C4 than what was intended.

Notes[]

  1. Here is the test method to deduce C-4 health value : place a C-4 brick, then shoot it 3 times with a 200-damage weapon at point blank range. Then, shoot one more bullet : the C-4 detonates, meaning its health is 800 or below. Then, do the same thing, but fire the 4th shot right outside the maximum damage range of the weapon used : there is no detonation, meaning the minimum health of a C-4 is right above 800. The gun used for this testing was the Manticore SX40, fired at 5m for "point blank range", and at 17m for "right outside the maximum damage range", which is 15m. Date of test : July 06, 2022.
