I am a huge fan of 3D FPS games; Duke Nukem, Serious Sam, etc. After 4 or 5 years ago I started looking for all the ones I missed. back in the 20th. Found Chaser on CD and others on Amazon. Like some of the Duke Nukem add-ons there were compatibility problems with Windows XP and 7. After finding fixes I played it through to it's miserable ending. I enjoyed the story and game play right up to the flat ending clip. The beginning parts of the game have an interesting unique scenario and each section of the game offers a new challenge of some kind. Good noisy fun right up to the end.
One of the few FPS games that shows a mature sense of humor and adventure. Lots of fun with bathrooms, mirrors and water fountains. GOG needs to get control of the Blizzard expansions Duke it out in DC, Caribbean Vacation and Nuclear Winter if they can figure out how to install them freestanding. Shadow Warrior would be nice, too.
