If we're talking about the greatest PC shooters ever, a few names will always come to mind. Half-Life is probably the easiest call. Counter-Strike definitely gets a mention. Go a little further back, and we have Doom to thank for basically the entire genre. But despite its devoted cult following, beaming reviews, and peerless reputation for bloodshed, one FPS game is often overlooked. With a new sequel on the way and updates coming to a close, this underexposed classic is briefly available to play for absolutely nothing, and you can buy and keep it forever for an extremely low price.
