An underrated Xbox exclusive. The gameplay is simple but engaging, the game has a good pacing and introduces new mechanics exactly when the player feels that he has already seen everything.
The characters are well written and, even if the plot is not original in the context of science-fiction, I feel that The Gunk has a lot of humanity into itself. Everytime I wake up in the morning to go to work, I feel like the two main protagonists.
Simple, but solid. Truly recommended.
