Hudson, a company that has made many games for wiiware has announced 3 new wii ware games. One first person shooter, a new Military madness, and Diner Dash. The FPS, Water Warfare uses water guns instead of combat guns. Sounds childish but it will have online play Death Match, Team Death Match, Capture the flag and assault modes. (I think it will have more but i am not sure)It will also have single player. It will bring lots of weapons or water guns in this case and 8 maps.Here a link to an article of water warfare IGN wrote.

The second one, military madness is a remake of the original military madness on the TurboGrafx16. You could get the original on the virtual console. This game looks sweet. Its a strategy games where you send out forces to beat your opponent.This is the article from ign.
Compared to Bonk or Bomberman, Military Madness probably isn't one of Hudson's more recognizable franchises. It does have a long history, though, going back to the TurboGrafx-16. The original was remade for PlayStation in 1998, and is now being remade again for current console digital distribution services. Military Madness is a hex-based and turn-based strategy game set on the moon. This summer's remake will feature the same story and maps as the original, but the visuals are getting a 3D polish.

The single-player campaign can be played on normal or advanced difficulty. Advanced uses the same maps but ups the enemy count. Everything is rendered in 3D now so players can zoom in for a close look at the battlefield and rotate the map. We were playing the game on an Xbox 360, where the L stick rotated the screen, the R stick zoomed in and out, and the D-pad moved our selection icon around the grid.

No new units have been added for this remake. Players will have at their disposal tanks, infantry, and long-range vehicles. A battle is won when either the enemy is decimated or its headquarters is captured. Like other games of this sort, adjacent allies will provide a support boost when you attack or defend. Your surviving units will level up and become more powerful over time.

Up to four players (or AI armies) can skirmish in local and online multiplayer. Strategy games can sometimes drag on for too long in multiplayer matches, so Hudson is adding the ability to set turn length or a maximum number of game turns -- when all turns are up, the player with the most points wins. We will also be able to use powerful commander units in multiplayer, and customize them with 20 special abilities. In player matches, all of these abilities will be available to every player. But in ranked matches, half will need to be earned.

The visuals we saw were decent but not impressive – perhaps because they were programmed for both the Wii and the HD consoles. We also worry that, at least on the 360, navigating the grid with the D-pad could become tedious. But this series does have a strong strategy pedigree and has received positive reviews in the past.

Hudson says Military Madness will be identical on all three platforms, except for a few multiplayer maps that didn't make it into the WiiWare version. You can relive this classic or experience it for the first time this summer.
The third one is the original diner dash.
