A video showing the C4 weapon type and some of its abilities.
C4 is a trap weapon, similar to the exploding Barrels. They are weaker in terms of damage output, but have more tactical purposes to them. They have double the base ammo of Barrels, and as such can be used more freely for loud distractions to draw enemies away from an area.
C4 Competencies also cause placed C4 to lower enemy damage through Blast Shield and Ion Choker Competencies.
Competencies shown in the video include:
Quick Place - Lowers Speed Counter reduction when placing Barrels or C4 in combat. C4 Chain - Each consecutive C4 explosion in a single triggering deals increasingly more damage. Can reach very high levels due to the large ammo count of C4. C4 Breakthrough - C4 attacks ignore enemy defense. Blast Shield - If the user is in range of their own C4 and the enemy is not, user reduces damage from that enemy by 80%. Situational, but very useful for long range combat against multiple snipers or Rocket Launcher users. Ion Choker - If the enemy is in range of the user's C4, their damage output is cut in half. Useful for prolonged battles.
