Crossfire, the totally free massively multiplayer FPS

This is the best PC game I've played since Counter-strike: source, if you haven't played it you should try it out. You can check it out at http://crossfire.subagames.com/index.aspx

It takes up under 300MB, and requires at least these specifications: 1.5Ghz, 512MB ram, a geforce 6600 or greater. However, my computer is 1.4Ghz.

It's not an empty game without any features they just depend on people to buy extra points that you can earn by playing anyways to buy extra guns in game, it seems to have more content then counter-strike: source in every way.

• More maps that are all great
• Anti-cheating protection
• Hip firing only and sniper rifles zoom at 2 levels just like in CS.
  
• More game types such as Team death match, Elimination, Search and destroy, and Ghost mode which is like search and destroy except one team only has knives and for the most part they are also invisible, unless they are running.
  
• More guns, you start with a M16 and a m700 sniper, but classics from CS like the AWP, M4A1, AK-47, SG552, AUG, MP5, P90, Desert Eagle, and P228 have all returned, with many more guns have been added such as 2 versions of the SCAR, AK-74, K2, K1A, Uzi, Draganov, XM1040, SPAS-12, M9, M60, Smoke grenades, frag grenades, and a great knife system.
• Customizable characters
  
• More ways to connect with friends, adding them and whispering them
  
• Built in clan support
• Clan leader boards
  
• Centralized servers, ones specifically for low ranked players as wellg
  
• Online forums
• A money system in game, you buy guns and equipment and you make money by winning matches, but your guns begin to wear out and you pay to repair them with the money.
• You can also buy even more guns by supporting the developer by buying points on thier website to buy extra in game points for guns or custom gear.

This game is great, it makes me not feel so bad about breaking my power brick for my 360, even if my laptop only plays at 20 frames per second sometimes.
