The year was 2000. Half-Life had already taken the world by storm and the prospect of modding the game was increasing in popularity. Counter-Strike was one of those mods. One of the most popular game modifications ever, Counter-Strike blended chunky weapons with rewarding team play, with the goal for counter-terrorists in most of the maps to either defuse a bomb, rescue hostages, escort a VIP to safety or prevent the terrorist team from escaping the area they're in. If you're on the terrorist team, however, the team goals are the opposite, naturally. One of the things that shines about Counter-Strike, though, is the amount of possibilities available. Don't feel like storming the enemy base guns-blazing? Why not sneak in via an air vent directly connecting to the room that the hostages are being contained in? Or perhaps you could draw your enemies out then snipe them from a distance? All the different ways you can win the match is ground-breaking. This, along with crisp, timeless graphics, a great selection of guns and the need for true teamwork, make Counter-Strike one of the best games of the decade.
