Just when you thought you've seen the last TIE variant released...
A new modeler, known as "FunkyFreshMan" on the XWA Upgrade boards, has posted his first work, a (you guessed it) TIE variant that was (eventually) named the TIE Archer. Check this thread
for screenshots of the craft at various stages of its creation (the finished product appears near the end), and you can download this bad boy at Vince T's X-Wing HQ
(linked page also has a backstory, which is also in the OPT's "read-me").
