Like every RTS game, you will need to build up your army through units. You will have to have a headquarters, barracks, airfield, armor base, artillery base and you can create extra buildings like administrative buildings and prototype research facilities.
You will need to farm money for the units by building supply trucks to run from supply depots to your headquarters. You will have the ability to create extra headquarters to make supply runs shorter. Each building than gives you the abilities to create individual units depending on the era and upgrades.
Barracks allow you to use ground troops and recon vehicles. Armor bases allow you to build Tanks and if you want planes you need to build an airfield. You can than upgrade your units. You want to upgrade the B25 Bomber to a B35? Pay the extra $50 and now you can have the B35 for the rest of the mission.
A RTS wouldn’t be complete without a online mode. The online mode is very competitive and challenging. R.U.S.E. was released in the fall of 2010 and just getting into the game a few months back has made my online matches difficult. Playing against veterans of the game hasn’t been easy.
Online allows you to play 1 on 1, 1 on 2, 2 on 2 and Free for all games up to 4 players at a time. You have dozens and dozens of maps and scenarios to pick from. You can choose the era, size of maps, time limit and which faction you want to play as. Even more maps are available through DLC however I chose not to purchase them.
