Now that i remember, it was not 1 hit kill everytime, sometimes it was heavy damages only, at the time we thought it was some random critical hit (and yes, friendly fire was turned off). However, the damage is still being added to the variable, and once the player is hit by any monster the cumulative damage will be processed all at once. This also includes any explosive fired by the player itself. They most likely made the 'ifhitweapon' return false if the source of the damage is also a player and friendly fire is turned off. When a sprite is damaged, the amount is added to a variable but the damage is only processed when a 'ifhitweapon' returns true in the CON code. I remember that it was quite frustrating, never happened in single player, maybe they thougth that the game is more interesting in Coop since the players can respawn without restart the level? In the original version i always wondered why in Coop the aliens are able to randomly kill a player sometimes, i mean no matter the health or what kind of monster shoot at the player, ie: Player 1 and 2 both at 200 health, a Trooper or whatever monster sometimes will 1 hit kill a player, someone know if maybe this is a bug or is this made on purpose?
