A sincere tribute to the old school platform game.

While Unit 4 has some really neat ideas, it barely misses the mark and will probably only attract nostalgia from diehard retro fans. In its current state, all the polish in the world wouldn't address the key issues I have with this title. To put it simply, this game's co-op isn't a big enough change from the retro titles it draws inspiration from.

Unit 4 is a fun old-school style platformer that requires various skills accessed by scrolling through four different characters. Its infectious humor and varied platforming challenges makes for a good time, but the fun is tempered by the challenge of making it through areas of increasing difficulty with only one life available; some sections will require numerous repeats from checkpoints. The game's difficulty level also ramps up early on, guaranteeing some trying gameplay for much of the game. The game's achievements are nice mix of easy and difficult, providing a nice selection of challenges, but with the 100% and no-dying-allowed boss fight requirements, it will not be a fast or easy completion except for those with amazing platforming instincts. For those who enjoy a good old-fashioned platformer, Unit 4 is one to keep in mind next time you're looking to buy.
