Alien Chaos 3D is a worthy addition to the Nintendo 3DS eShop roster. It's a retro-inspired adventure, high on action and pulls at the nostalgia strings. Worth considering at the price, but leaves little replay value unless you are keen on investing time in getting those high scores.
With the addition of a fun multiplayer mode and some clever challenges to keep a player coming back, this could have been something special, though sadly it ends up a simple game with solid mechanics but little replay value.
Unfortunately, the game's limited modes and the absence of multiplayer result in an experience that is lacking in replay value. Nevertheless, it's a valiant effort from Ludosity and well worth your money if you're looking for a solid pick-up-and-play title to indulge in every now and again.
