What each player can do here

P1 · Player 1
  • Silver Surfer: his signature cosmic blast hits several enemies.
P2 · Players 2–4
  • Rocket Raccoon: only some of his random grenades are nukes.

If your skill levels differ: A hero still earns experience when you lose, so a failed attempt is not wasted; the newer player can keep going without losing progress. How to split the roles

The citadel

Part 1 of 1. Reach MODOK.

  1. BothChallenge: let Galactus's laser blasts finish ten enemies; weaken them and lure them into his shots.
  2. BothChallenge: ten Silver Surfer cosmic blasts and three Rocket nuke-grenade kills; keep throwing grenades.

Where people tend to fall

  • One guide (DualShockers) on the boss, MODOK: dodge the adds he spawns and break his stance with a timed counter; it calls the fight a bit tougher than the final boss.
