Besides sequels to Capcom's AvP, Jaguar's AvP, Alien Trilogy and Predator: CJ, I would like to get an Aliens game which is made in a style of classic Resident Evil games (RE1-3) i.e. with a tank control, fixed camera angles, atmospheric music, pre-rendered backgrounds, 3D stuff (characters, items and enemies), iconic elements taken from Aliens 1986 and rebooted plot (alternative universe).
Also an AvP 2D pixel art top down twin stick shooter.
