Game/App counter? Or something similar.

Probably boosted for it. Did you watch the replay of the game to see what he did to get it?

Oh ok. Sorry for misunderstanding what it did. It just happened in the game I just played and I thought it was a nuke. But your right, it just killed every one and then every one got back to playing. But it made the map darker. It was pretty cool but the
guy is either incredibly good or got really lucky.

M.O.A.B.

Doesn't end game, 25 kills with just you and your gun, killstreaks don't count. I haven't seen one yet.

I watched the replay and have my questions about what he did. It seems like he played a very small part of the map. He had a silenced assault rifle and was probably hidden to all air support and uav's. Without question, he hid and nobody faced the guy face-to-face
but instead all of his kills were either long range or a guy's backside. He did kill the same game numerous amounts of times but in no way did it look like he boosted for it. The only way I could see that he boosted is him in party chat and having somebody
on the other team calling out positions of guys.

i expected the mortar to be something similar to the mortar binoculars in bfbc2. seems everything in this game is allowed to be countered. except the stationary AAs. lol nd i think that since its only for spawn protection. the mortar is still a viable support
tool on occasion. like maybe rush as attackers
