Mine Shooter is a first-person shooter set in a Minecraft-styled world, and it takes the arsenal seriously: assault rifles, pistols, sniper rifles, shotguns, SMGs, grenade launchers and a bazooka, plus grenades and a knife.
The enemies come from the same source — creepers that explode if they reach you, skeletons that shoot back, stone golems that soak damage, and zombie hordes — so each type needs a different weapon and a different distance.
Assault rifles, pistols, sniper rifles, shotguns, submachine guns, a grenade launcher and a bazooka, plus grenades and knife attacks.
Kill them at distance. They explode on reaching you, so they're the priority target regardless of what else is on screen.
Yes — the blocky graphics keep it light enough for low-powered machines.
