It's been hinted at for some time, but Hudson have finally revealed Onslaught - an first person shooter on WiiWare with an online multiplayer component.

"Being the first FPS on WiiWare, Onslaught gives shooter fans the action you’ve been waiting for. Taking advantage of the precise motion controls of the Wii Remote, you’ll be in full command of your soldier as you tread through treacherous terrain. The action stays tight by aiming with the Wii Remote. You'll need steady hands if you're going to survive the horrors that await. When running low on ammo, give the Wii Remote a shake to get back in the game. When the odds get overwhelming, a supply of grenades will keep enemies at bay by throwing them using the Nunchuk. Get set to play an FPS unlike any you’ve ever played before!"

It's looking okay given the 40 Megabyte limit, but as with many games it'll all be up to how it looks in motion.

The most interesting thing about this will be that, considering all WiiWare Hudson games have been created in Japan, this will be a Japanese made first person shooter. Now that's something to keep watch of.
