"Tactical first-person shooter" computer game.
Enemy military forces consisting primarily of infantry but also including tanks, helicopters, and other military vehicles.
Voxel game engine allows for nearly unlimited draw distance, providing for expansive outdoor environments which vastly exceed the size of levels in many games with polygon-based terrain, just look at the screenshots. Although the base terrain for each level is only a square kilometer, this is tiled in all directions, potentially allowing for literally unlimited travel. Due to the expansive size of the environment, gameplay is focused more on long-range combat, and many gunfights take place at hundreds of metres. That being said, every now and then the player ends up using a shotgun or a knife, so yes, you can get rather close to the enemy as well.
