Alien Breed The classic top-down shooter comes to the Playstation Network. With the PS3 and PS Vita version the developer introduces additional features, such as the ability for players to team up on either system via cross-platform play. There is also ad-hoc and online co-op multiplayer for PS Vita, and local and online co-op multiplayer for PS3. There is also a Cross-Platform Continuation Play in the mix too, allowing players to carry on their PS3 save game progress on their PS Vita and vice versa.Alien Breed is a decent package and great love letter to a classic arcade game but that’s all it manages to be. The inclusion of multiplayer goes a long way to make this package worth the price but if you are looking for something more in depth you may want to look elsewhere.
