It's been RELEASED!!!!
The team released the Infantry BETA on 1-3-'08
After a conversation on the public IRC channel i find out why there aren't any vehicles. They told me that *SOMEONE* has set a deadline so they didn't had enough time.
Altough One_Winged_Angel of the Reborn team has added vehicles in his own version within ONE DAY!!! They're now thinking of a update for the Reborn BETA to add the vehicles.
