Let Them Come: Onslaught is a quality bullet heaven experience. It offers a lovely art style, an exciting soundtrack and an intense difficulty with well-designed level progression. It is, however, a bit on the short side, with only 4 levels, 2 characters and not a huge build variety. It’s a game that is quite close to greatness, but it will need a bit more content to truly become an unmissable classic survivors-like experience. I still feel like recommending it to fans of the genre, as its gameplay loop is one of the best ones on Xbox right now.
