Onslaught was only announced for European/American release about a week ago, but it's already available now! The game is, shockingly enough, a first person shooter - The first on WiiWare. In fact, even the download services on the PS3 and Xbox 360 don't really have any FPS games aside from ports of old ones. Aside from featuring a single player story mode, Onslaught also has a 4-player online co-op mode, which certainly sounds very promising. Onslaught costs 1000 Wii Points.
Today's other release will probably not excite as many people. Pop-Up Pirate! is based on a classic "board" game by Tomy. You are presented with a pirate, who is trapped in a barrel with various openings in it. You and the other players take turns sticking swords and other objects into these openings, hoping that it won't hurt the pirate. As soon as somebody does hurt him, he or she loses! This WiiWare version of the game doesn't really seem to be anything more than a digital version of the game, but it only costs 500 Wii Points.
Certainly a surprising week - Who expected Onslaught this soon after it was announced?
