Episode 4 ends the experience on a good note and having seen the conclusion; I would say that Resident Evil: Revelations 2 is another successful entry in this side series. It excels in replay value and overall fun value, and the unlockables and the Raid mode pushes the value over the edge.
Episode 3 picks up the pace and is where the story is starting to hit its stride. The balance of puzzles and combat is great, although Claire's section is far more enjoyable than Barry's. There's a lot riding on Episode 4 next week to bring the game to a satisfying conclusion.
A different episodic experience that excels based on its gameplay and not its story. The hook has been established but the next installment of the story is going to have to come harder.
