Hereby I make a suggestion to be bringing specific missions, unlike the common missions in single player. Inevitable for these games should be contributing to teach players how to aim and shoot. There are several games on the internet in the same style as ShellShock Live, as DDTank, Browser game, it has rules for certain angles within the game (Find out for yourself, there are 3 so far and only own one in my knowledge). If this is cheating, tell me how to solve something that is not on the PC and with infinite resources to make one for myself.
I use ruler and when I say or someone realizes themselves against me and call me a cheater or 'hacker'.
