Yep a RTT game.
Tanks do not have healthbars, all their armor plates have historical values + the calculation of the angle of impact of the projectile. You also can shoot down the tracks of a tank or hit the engine, disable the turret and so on, ofcourse tanks with flat angle armor have an advantage not only in mostly thicker armor but also on causing recochets.
Soldiers do have healthbares so you know how they are feeling
Since the game has impressive physics a piece of a housewall falling down on a soldier will kill him instantly. Mostly those houswalls fall down while a tank tries driving through it
Sometimes a soldier gets killed when a recochets flies in the wrong direction and hits him by coincidence..., every projectile is simulated correctly and a soldier does not "play" being hit like in some other games, if he's hit he is really hit like in a FPS.
The 25% belong to the flag in the middle, the gamemode played on the screenshots is a faster one. There is one flag in the middle of the map, the team with more soldiers in its zone is raising the flag slowly, the one who brings it up to 100% wins, if the time doesn't end earlier.
