Unfortunately, both for you guys and for myself [as they are my favorite weapons], Rockets and Grenade Launchers won't be in BETA 3, both for production reasons as well as gameplay balancing issues.
Too bad, I loved the Grenade Launcher, but given the quality of the work you have done so far for Beta 3 (it must have taken a LOT of work, in my humble opinion), I don't mind waiting more time, if that's what it takes to make it perfect.
Perfect; we can see from the feedback the devs give us (with the media releases and others things) that there is a lot of work and perfectionism behind this mod. In fact, I think there is more than in some commercial games, and that should be taken in account. And it's not only the maps being well made, the models well made, the sounds well engineered, its also, as killermonkey said (I think is was him) about the fun factor, and this mod has a lot, even in the buggy Beta 1.1.
I'm sorry if I veered off-topic, but though of saying this here, now that I was writing.
