Knock'em All is an interesting first-person shooter game, and it is also a 3D arcade game. In the game, there are many robots attacking you, you need to launch them out of the platform by launching balls. These robots are very fast, so your launch speed must also be fast. The gun can advance automatically, you just need to keep going to shoot. Keep calm, aim, and launch! Most of the time, shooting them all down is better than shooting them one by one because of their running speed.
