Balance Update

The Missile Launcher and Grenade Launcher have been rebalanced.

Instead of a limited number of shots per match, these weapons now recharge automatically with a 90-second reload timer.

They are extremely powerful weapons, so the longer recharge keeps them impactful while allowing multiple uses during a battle.

Strategy decides everything in Artificial Extinction 2.

The battle begins again March 9. Will new champions rise?
