Games like Alien Revival - Episode 1 - Duty Calls

Initially very much First Person Shooter, with collectables, series will develop into more adventure/task driven whilst still keeping the FPS element. Episode 1: Duty Calls - Join the government service as a lone agent... Society is breaking down, citizens have defied the law and armed themselves, anyone you meet is suspect, and a viable target, just get out there, collect various items and eliminate any and all opposition. [NB: E2 will be released as a free upgrade to E1 to provide additional content, collectables, achievements and adventure elements]
