Already plenty of ways to defrost. Even just bumped up the range of the sentry a bit. The easier I do make it to defrost, or more ways to do it, the more it becomes tdm.
I really dont want to start adding too much at this point. Beta 10 will be primarily compiling all the existing bug fixes. Also fixing some missing images and stuff like that. If I am to continue with ftag, in some other game, then it would be from the ground up and as far away from standard tdm as possible. No bullet weapons but a few freeze guns. Yes a GL-like weapon (or something like that blob-shooter from UT) that lobs freeze canisters... but means you get no freeze gun. So you dont freeze with a couple bullets. You need to keep a freeze ray on his torso for a second. But 1/2 frozen players can only 1/2 as fast stuff like that. Almost like the opposite of defrosting.
Anyways, long story short is that I dont want to start thinking up much more new shit to add. Done enough.
