Heh, even I can try mapping...at least concept wise, with experienced mapper revisiting it for balancing.
So...what other ideas we can think of? Legacy T-Shirts giveaway ?
On a more serious note - maybe release Legacy with some new bonus features added (to add replay value to existing maps, rather than making new)?
For example randomizing surprise mutants (especially hanged, caged and lab ones) can add much replay value as now you can't "learn" the surprises...simple to code in - in just a few days, perfect idea methinks.
Also from all the walkthroughs - chaingun is "Legacy" biggest weakness - this weapon is so much preferrable over other weapons...since found, Balames and others used only chaingun, and it looks too easy. We might add some balancing elements to it.
I can improve some art, I recently made better headshot frames and better knight breaking frames...Also better use of wall transparency.
