Rivality is a free to play military themed browser based MMORTS title developed and published by FunRock Media. The game features 1 huge world where all players play together, you're given a large area or turf in which to build your base and army.

The game offers restrictive type base building, allowing players to choose what priority to give each construction project but allocating it a build space for you. This avoids any chance of misplacing buildings or factories which means the player can spend more time going forward and building up their base instead of rectifying previous mistakes.

Oil is the primary currency in Rivality and players that learn to hoard this resource will be able to construct stronger buildings and train more troops. You can gain oil from building oil rigs and refinery's and then either sell the oil to other players or use it yourself to build units and other buildings. You can also choose to attack another players turf in an attempt to steal their oil or cash rather than collecting your own resources but this comes with its own risks.

Rivality offers players the chance to use a variety of different troops and units, all with unique strengths and weaknesses. The outcome of each battle is dependent on what units you use to attack the enemy with, a large squad of rifleman don't last very long against an organized unit of fighter planes. As well as aircraft and infantry units, mechanical units are also available such as transports to increase troop movement speed and tanks to help deliver that killing blow.

The game is available for all to play for free however is does offer the option of buying VIP credits which you can use to pay for exclusive units or trade the credits for more gold and oil.
