I also found this, looks like he’s working for a mod :
Furst, Day One (that Killzone mod for RWR) has again been updated, making it compatible with 0.85 and bringing the total number of weapons to 15, including the M224-A3 (Rico’s gun in KZ1) the Crossbow, and the BLR-06 Hadra Multiple Rocket Launcher. Check it out if you want to play something similar to Killzone Liberation but involving large-scale infantry battles taking place in an open-world battlefield. Best of all, the devs of RWR keep improving and adding features with every update. It won’t be long before faction-specific weapons and vehicles (and even air support) get added in and we can have the full experience!
Mod thread is here:
Well, forget that, the models are going to be 2d models.
