Gunrox is a multiplayer-only turn-based strategy "squad tactics" game that went live in 2008. Each user account (player) is allowed to have a single squad of 3 units. Players can create game rooms and invite others to form matches, including 1 vs 1, 2 vs 2, 2 vs 3, etc. During battle, each player takes turn moving their units. Each unit has 12 AP (action points) that are used to move around, opening doors, picking up items, attacking enemies or healing. In basic mode, the game is won when one side runs out of unit. Experience is awarded to player, not to individual units, based on the amount of damage done as well as several other factors. As players gain enough experience, they level up, and each unit receive skill points and perk points. Skill points can be put in weapon skills (Melee, Pistols, etc) or support skills (Traps or Healing). Skill points will increase the damage and accuracy of weapons, effectiveness of healing items; also, more advanced tiers of items require specific levels of skill to unlock (10, 20, 30, etc). The game consists of several separate areas, which are unlocked by levels: Beginner area (level 3-), Clover Quarter (level 3+), Lost Beach (level 5+), etc. Games created in each area have a distinctive battlefield size, features and collection of objects. In addition, more high-level areas have more complicated game modes such as Free-for-all (last player standing wins), or King of the hill (win by capturing and holding the center area of the battlefield), etc. Besides fighting, players can interact with each other by talking, private messaging, trading weapons, forming clans, etc.
