I propose a plan to introduce the inevitable (come on, we all know it’s inevitable) Multiplayer Mode with a special mode that would see a Volcano involved. Imagine a mode that instead of simply teams of friends versus friends or Alliances versus Alliances saw a different win method.
Imagine a timer. The Volcano erupts at the end of the timer. Whoever has taken the most overall damage loses and their entire Strike Team engulfed in lava.
Or this could work as a Team Tournament where you fight with up a Volcano and the two Teams that make it to the top battle to the death with Fatality style finishes into the Volcano itself triggering special environmental death sequences.
