The base roster is great, but you really want to play as Venom and Silver Surfer. Here is exactly which missions you need to beat to unlock them.

The Cosmic Matrix has 101 rewards. Most are useless lore files, but we found every single Skin, Cheat, and Music Track so you don't waste your Cubes.

Grinding levels in beat 'em ups is usually a chore, but I found a way to max out any character in five minutes using Beta Ray Bill and a swarm of bugs.
