Alien Breed: Conflict (aka Alien Breed Action, ABC, or ABA) is a cancelled FPS in the Alien Breed series that was in development by Team17 in 1999 / 2000 for PC and Dreamcast. It was meant to be a follow-up to Alien Breed 3D II: The Killing Grounds, published in 1996 by Ocean Software. Sadly the development was cancelled as the size of the project was a bit overwhelming at the time.
We can read a short preview of Alien Breed Conflict on Computer And Videogames, but sadly only few screens are available:
ABC is a darkly futuristic, real-time 3-D strategy game. The player takes control of a small band of special operations soldiers as they fight for the freedom of their people. These guerrillas carry out dangerous missions behind enemy lines using guile, cunning, stealth and strategic abilities. Missions, including assassinations, strategic destruction, information retrieval and prisoner rescue, will be attempted by the player as he develops his skills of tactical combat.
You’ll get to develop your own characters with the skills you desire, deploy your units with predefined orders, command multiple groups, define your own tactics and select your weapons of choice.
The singleplayer missions in the game are said to be vast. Team17 will also focus strongly on multiplay and will run dedicated servers to save player stats and rankings.
