Garena+ allows you to connect with a global network of game players so that you'll always have someone to play against.
Garena+ currently supports quite a limited number of games but does include some major titles such as Age of Empires I and II, Battlefield 2, Bordelands, Call Of Duty: Modern Warfare 1 and 2, Call Of Duty: World At War, Counter Strike: Source, Call Of Duty 2, Left 4 Dead 1 and 2, Red Alert 3, Starcraft, Team Fortress 2 and Warcraft 3.
When you download and install Garena+, you have to create and account to log into the Garena network. You will be assigned an avatar that will identify you within the Garena community. You can instantly see who is online and which players are at a similar ability to you. Garena+ seems somewhat more focused on some games more than others though e.g. World of Warcraft 3, for which there is even an online video channel and high-level championship mode.
To communicate with other gamers, Garena+ has its own Instant Messaging and internal mail system and forums to discuss gaming issues. There's also a points system for those users with more experience and forum activity.
Garena+ isn't compatible with enough major titles but for those it does work with, it's a simple way of finding like-minded gamers.
