Cover doesn't count for much when the entire battlefield can be blown apart. A carefully angled shell might open a gap through a wall, bring a tower crashing down, or leave a rival tank stranded in the open. Sometimes it's worth aiming at the scenery instead of the enemy.
Unlimited money is already unlocked in this version, letting you enjoy the tank battles without having to grind for in-game currency. The real pleasure comes from experimenting with the destructible terrain, finding awkward firing angles, and watching a supposedly safe position disappear in a shower of voxel rubble.
