This zip for the mac?

I don't think so but if you look closely, the last post was 2 years ago so I doubt that this works with 1.0. You'll have to magic some compatibility into it.

It's fully functional with 1.0. Don't make assumptions, just test it.

i have to say, the sniper rifle seems to do squat unless you hit the ground under an enemy. the shot passes right through any enemy without even touching them. fix?

It does this for me too, but only when there is a lot going on on my screen. I probably wouldn't have even noticed it if it weren't from me reading your post.
Perhaps it is a lag-related issue with the high fire velocity?

edit: Oh ♥♥♥♥, this is my first post? I wasted my 3 years of lurking on this?

Actually it's because it uses a TDExplosive as the bullet, back in...build 23 - build 24(5?) TDExplosives still collide with actors, now they just pass through them. You could change the TDExplosive to an AEmitter, along with a few other changes that the AEmitter will require, or possibly a MORotating(not sure) as a 'fix'.

I wish he could have a (expensive) miniature-mini nuke. You know, like the UniTec nukes, but a little bit bigger?

Oh wow, I spotted this just as I finished the SC1 Gauss rifle weapon in my gunpack.

Nice.

I tried making a nuke way back when, but couldn't get the effect I wanted so I gave up. I haven't touched cortex command in years so I'm not sure how the code has changed, or even remember how to mod.

I just downloaded the newest version so I'll play it and if I get into I'll try to finish this guy.

Oh Gosh, you are back.

If you want, look at Online Tech, R.E.T.A.R.D.S, and Psy-Clone, for a few pointers.
Set aside that Cavecricket, weegee, and TLB are notable modders.
