Garena supports computer games like Warcraft 3 Frozen Throne, Quake 4, Counterstrike 1.6 and Source, Starcraft, Left 4 Dead and Call of Duty 4: Modern Warfare.

Each user has to register an account with the Garena service to use the software program. The software itself is divided into various rooms for the games which can be joined by the user. Each room is further divided into chat rooms of a maximum of 255 players each who can use community features like chat, private messaging or buddy-lists.

Games are started from these individual rooms by selecting the executable of the computer game on first start. Garena will remember the settings from then on and start the game automatically from then on.

Games can then be created and joined normally in the computer game that has been started (which is usually network play). Garena offers game leagues, clan creation, tournaments, a ladder and a client that is available in many different languages. The two main benefits of Garena are the community features and the network play (which removes the game key requirement for some games).
