Epic Games appealed to the community for a great name for a CTF map. From sixty names the developer team picked their top five:
CTF-Icarus (been used before, but such a good fit)
Finally they have chosen CTF-OmicronDawn, the name that were suggested by keyrat, who will be listed in the Unreal Tournament 3 credits.
The first three images below are from CTF-OmicronDawn, the fourth image is a concept art featuring DM-Sanctuary.
