I recently added this forum game thing named Army System. Basically, its a game where you buy different weapons and battle other members from the forums.

The different races are:
The Marines
Fort Knox
Homeland Security
NATO
CIA
Private Citizen

Basically how you play is you choose a race, buy some weapons and stuff, and then click attack to attack other people.

Things to remember:
• Your army size is based upon your number of posts on the forum.
• Buy weapons in the armory.
• The higher fortification you have, the less damage the enemy will inflict.
• The higher siege tech. you have, the more damage you will inflict.
• Get more soldiers by upgrading your unit production.
• Don't forget to train new soldiers.
• When you beat somebody, you steal their money.
• You can buy mercenaries.

The link to the game is in the menu bar at the top of the forum. It says Army system.
