Hello people. I was playing Crysis 3 multiplayer, team deathmatch (I cannot remember the map's name). I was using an Alpha jackal, then I killed an enemy player, picked up his Scarob MK2, then I somehow became invicible after I cloaked, put on armor, then in normal mode. I even stood still for about 20 seconds, three enemy players ganged up on me, and could not kill me no matter what they hit me with. I'm not a hacker, nor do I have any intention of becoming one, but I have no clue how it happend. Can anyone shed some light on this?
