Works on vehicles will start the 4 of September and it will take around 4 days. Until that date, work is suspended for holidays.

For Multiplayer is a bit more difficult;

The way we made the game makes integration of multiplayer really hard. We should finish the game in SinglePlayer before, and then make another identical build for Multiplayer. So until the game is not finished, multiplayer will not integrated. So, meanwhile we will make singleplayer more funny and playable.
