Aim hacking
Instant kill
Wall hacking
Noclip hacking (being able to be anywhere on the map, they are usually found to be inside buildings or brick walls etc.)
It would be extremely appreciated if there was more focus to fixing these exploits that players are using because I think it is safe to say that the Crysis 2 multiplayer fans can only tolerate so much.
Another issue that I have found is how crap the spawns are. Seriously, I have always either spawned in front of the enemy, who without hesitation kills me, or I spawn in the vicinity of an enemy... who usually runs into the room and kills me... I am aware that the maps are pretty small but this can be solved by either fixing the random spawner, or making the maps bigger...
