-------------Features:-------------- zsecs can throw grenades.- zsecs kill the player instantaneously if they come close enough.- zsecs will generally act smarter: they will try to retreat after throwing grenades. They will seek cover at certain distances. If near to the player, they will try to approach you for an instant kill... However, sometimes they have less bright moments when they blow each other up with their own grenades.The behavior needs to be tweaked based on the design of the level you want to use them in. The provided settings work well in the map game/alphalabs1. If the corridors are larger and wider, the distance settings need to be increased. These settings and other tweaks can be controlled through the entityDef monster_zsec_pistol.
