Hi everyone! As a newcomer to X-division, i asking for help in some gameplay aspects: 1- is there some kind of guide to read or watch, how to break into UFO? because almost every time,the guy who open the door get killed, is main door destructible? 2- does weight of item/weapon affect to TU consumption when i move them beetween backpack/belt/ground? 3- is crouch/stand action cost 10 TU`s? is that OK, or i have some kind of bug? I thought it cost less TU in vanilla game. I would appreciate any response or advice.
