Build and Shoot

The game is Running With Rifles. Though the game makes you imagine yourself running around with a rifle similar to aos's it isn't really like that. It uses voxels. But the terrain isn't blocky. Only the characters are.

Try out the demo. The game is also moddable. But be warned, it's not free. It also supports 600 bots running around on one battle field and is also multiplayer.

I tried it, and I like it.
