does this client include the game?

[ElEnrique]

I ask because at the time of downloading it starts to download me something of 2gb, but I do not want that, only the client since I already have it on steam

 

[Vertigo]

Yes, this client includes game. But the game version is v34.
Steam CSS and ClientMod are separate versions of the game. Don't mix them together.

ClientMod is the same standalone client as the Steam version and v34. ClientMod can only be played on v34 servers.
