|— Weapon Description|
The M116A1 is one of rarely seen grenades in game. Effect of the grenade is the same of MK3A2 except for the damage. The blast radius is very narrow and it has very little use in game. However, it is good for breaching rooms and temporary blinding enemies in an area (makes their entire screen white), in which you can kill them easily without the risk of being suppressed by enemy fire. As said before, the range is very small, so the chances of directly hitting the enemy and blinding them with the full blast is little. The fuse time is roughly the same as the MK3A2.
Contrary to popular belief flashbangs are not effective at Tower Defense or clearing campers. See:
