People who searched for this game do not need to read reviews as are they have probably already played the game more than a decade ago and were driven here by nostalgia or some exciting memories about it.
Others, who see this for the first time, should bare few things in mind - if you never heard of logitech MX series of gaming mice, or how to use F6 quicksave button, maybe this is not a game for you. In this game there is no regenerating health, no automatic cover, and no rushing through the level. Crosshair doesn't take half of the screen and you can't play it with the controller. It's all about skill and precise aiming. Most enemies fall after one precise headshot and good aim and reflex is far more important than how full is your armor or health bar. The gameplay feeling is almost like that of good old Counter Strike or Rainbow Six. In short this is more of a tactical shooter - Call of Duty fans should just skip it.
On the other hand, if you are familiar with this type of games, you will be treated with very satisfying gameplay and you won't have too much problem going through levels. Graphics stand through test of time and game runs pretty well on modern systems. The storyline reminds of Total Recall, but can get pretty nonsense at times, and Mr. Chaser's choices are sometimes like those of 4 year lobotomized child. However the levels and gameplay just gets better the more you play it.
Warmly recommended for oldschool gamers, especially considering price of few bucks!
