A PvP setting above Extreme would be a great addition, where players can be killed by moving drills, saws, tank shots, or other hazards.
This would add excitement, especially in private servers or public tank battles, where on-foot players could face real danger instead of just losing their vehicles.
Features like being shot by tanks or run over after being flung from a car would bring a sense of urgency and immersion.
As an optional setting like Extreme PvP, it has great potential to enhance gameplay and create more intense scenarios.
