Play through the Marvel Universe as a member of the Avengers or other Marvel Universe characters in this Lego game. Whether your favorite character is Tony Stark because you envy how he picks up girls, or Mr. Fantastic because of how he can stretch...himself, you can be happy knowing that you can play as everyone. Fight against Marvel Villians as super heroes and use your super powers to solve puzzles with legos. Their basically guide you through everything since each level is so small but it's still fun nonetheless. It's currently on sale for only $5 from GetGamesGo so I'd suggest picking it up. It comes with achievements on Steam and you can play multiplayer or co-op. In this, there is local co-op with split screen.
