nice idea, and wouldve been better if a proper company produced it, not enough thought was given to details like ammo, health and aiming. imho the patches dont make it much better.
humans take way, way more than 3-4 shots and you also reminded me, the random respawning of ai is beyond ridiculous!
Survive 2 full clips? Your aiming must suck.
I can drop most with 1 or 2 well placed rounds. Like i said, you have to compensate for the mavity depending on distance, and also wind can affect it, just not as much.
Regarding respawning? Could you imagine how bad it would be if they didn't respawn. The place would be like a Ghost Town with nothing to do except walk free and look out for anomalies.
