Suicide C4
Suicide C4 is a light gadget in BattleBit Remastered.
It has only 1 button - rmb, on activation this gadget will explode with 300 damage to infantry and your character will die immediately, however your allies still can revive you. Explosion radius is really really small, so you need to always remember that.
Strategy
This gadget is useful for snipers. Since you most likely will stay on a single position for a long time, then there always may be some enemies around you. You probably won't kill every single enemy if that happens, so if you stuck among some bad guys - just grab suicide c4 and run to the closest enemy, then on only 1 click you will kill your character and may kill the enemy too. But always remember about the explosion radius.
Suicide c4 is just a fun gadget. Use it however you want, really. It could make your day better because of how stupid but effective this gadget works.
