Pick it if…

  • you want to fight, blast and test your reflexes
  • you have time for a quick session (under an hour, or endless arcade fun)
  • you have a friend to play against
  • you've played the Genesis hits and want something less obvious

Maybe skip it if…

  • you want depth and variety over simple, satisfying brawling

What playing Alien Storm is like

Beat 'em ups send you down scrolling streets fighting waves of thugs with punches, kicks, throws and grabbed weapons. Most can be finished in a single sitting and shine with a second player.

Tip for newcomers: Avoid getting surrounded: keep enemies on one side of you and save your special attacks for crowds. Bring a friend if the game supports co-op.
