Windows and Linux¶
The ET: Legacy client does not work with all available mods. Please check the below table to find out which mods are (not) compatible.
|Mod||Version||Client||Server||Client (64-bit)||Server (64-bit)|
 ETPro does not work with the ET: Legacy client, read more about that here. ETPro servers without PunkBuster start fine.
 True Combat: Elite and True Combat: CQB need server patches (see etlmodexep). For more information about these mods, see the TrueCombat Mods page.
 The 64-bit version of ET: Legacy (which is only available for Linux) is only compatible with Legacy mod (default mod shipped with ET:L) and ETrun.
Mac OS X¶
Please be aware that the Legacy mod is the only compatible mod with Mac OS X. Other mods will most probably not work unless they provide an updated version. Also, the binaries are only compatible with Mountain Lion (10.8) or better.
Furthermore, since there is no Omni-bot available for Mac OS X, you will not be able to spawn bots.
