When this new game mode appears, i think will can be up on my limits. My bad, on this new game mode u cant just kill everything to stay alive (like survivor missions), u need FOUND this stimulants, to your energy dont go to zero! I want to die on mission, not for the energy loss, but for the ENEMIES! Really, whats is the big deal on this new mode? the enemies or the oxigen2, identical to survivor missions? oh, there is the "new mode"??? I WANT TO TEST MY LIMITS, no to found stimulants EVERY STAGE... thats boring! I WANT TO GET KILLED BY A ENEMIES! I WANT ENEMIES ON MY HEIGHT! I WANT A TRUE CHALLANGE!
