I highly and unironically recommend you play this video game at least once in your life, it's an absolutely atrocious failure of design but it really makes you think, changes your perspective on a lot of issues and areas of game design in a way that you just can't achieve by playing (m)any other games.
Oh, and yeah, chaser was developed by Bohemia Interactive, yes, that Bohemia Interactive. Arma is a chaser sidegrade.
