Mnyeahh...I would be happier with it if it DIDN'T have a 'wacky' tone. I want a serious zombie RTS. That would be awesome as hell. Are there even any horror RTS games? I don't mean ones with horror-based units or environments. I mean, an actual zombie-based RTS, with you managing survivors, that could be terrifying with the right tone.
Hell, even with you controlling zombies it could be scary. Watching your zombie horde tearing into survivors would be simultaneously satisfying and disturbing, and that would be awesome.
