Mental Gun 3D is an FPS that lets you play online against tons of other players. The rounds are short and sweet, lasting only about five minutes each. The team who wins is the one that's taken out the most enemies when the time runs out.
The controls in Mental Gun 3D are simple. With your left thumb you control your character's moves, while you aim and shoot with the right. From the options menu, you can choose if you want to turn the automatic shooting and aiming on or off. It's important to consider that the aiming 'help' is pretty extreme.
When you start playing Mental Gun 3D, you only have an assault rifle and a handgun to use. However, as you play and win rounds, you can unlock tons of other weapons like sniper rifles and shotguns.
Mental Gun 3D is a great multiplayer FPS that has simple but nice-looking graphics, and a straightforward gameplay. It's the perfect game for playing a quick, five-minute 'team deathmatch' anytime and anywhere.
