all the logic of this game yet fits into these:
randomize bullet_quantity_to_kill (1; 100) & distance_to_oneshot (0; 1000)
=totally unpredictable (& certainly nothing related to realism at all)
One more unexplainable AI behaviour (that came from Ins-2) when some player stands between you and the bot, bot shoots you before, farther you are, more precise his fire is. Bot may completely ignore the closest player.
Completely agree to all said above,.. and disappointed. Didn't expect to see the very same sins in a "new" game, occured in fact just a new wrapper for them. Plus one thing that completely contradict to the logic are windows - the chance you ll be shot there in short time is higher than when you stay on open places outside of the building.
