Heh, thx for the file, i found the grenades. Its just what i thought it would be, itsd an PCO, with the shape of an grenade. They made it so that it dies after six seconds (critical damage is set at max. hp), and speedmod is 0, so it wont die from the fall. When its health is down it explodes. Thats all there is to it, quite simple and not usable for anything like we want to do with projectiles

. Maybe one could make an effect which spawns that stuff, but i think thatll give client trouble.
BTW, you can find the codeourself, in the map's rfa find the objects.folder, inside theres Bombs.con, its all written down there. BUt i cant find wheere they declared the spawners for them tho. Most prbably they spawn the rotational object they made and put it in objectspawn.con or more likely staticobjects.con, but i didnt see it (didnt look very well either:P)
