Take on X-Defense Mode in Marvel Heroes
Marvel Heroes gets what may equate to its own Horde Mode this week with the new X-Defense mode, challenging players to take on endless waves of powerful super-villains to protect students of Xaviers School for the Gifted and survive as long as possible. After defeating one wave, a new one more powerful than the last will spawn. As the challenge increases so does the loot quality.
You can sign up to play for free and try out X-Defense mode on the Marvel Heroes website. How long can you last?
