Wow,some very good responses here, complete with some perspectives that haven't been considered before.
Dodece - I can't say too much on the game without giving away some trade secrets, so, sorry for the vagueness. =) As for weapons, here's just a short glimpse - Molotov cocktails and broken defibrillators are in. I say no more!
Hephaestos - interesting breakdown solution for release/sales. Definitely something to consider. Btw, a free demo is planned. My only concern with WiiWare and addons is trying not to usurp all the Wii memory. I really am hoping that Nintendo does the right thing and puts out a USB hard drive
to all else - thanks for the input/feeback. My years of gaming and being a beta tester have taught me the value of player input, and you have been heard. We're not making games for us, we're making games for you =)
