Games don't always offer the possibility to change the language in-game.
For this reason, we have built a language selector tool for every Giveaway game.
Navigate to the game installation folder. For example, C:\Program Files (x86)\GameSessions\Zombie Army Trilogy.
Launch “Language Selector”. Pick the language you would like to use, then click on “Download”.
This might take a few minutes to download and install.
The language in-game has now been changed; you can launch the game again.
