Muscle March posing on WiiWare

Muscle March presents outrageously clad bodybuilders striking dramatic poses and crashing through walls to catch a protein powder thief. As such, this week's headlining addition to Nintendo's downloadable game service is clearly not for everyone. However, those who may be interested in Namco Bandai's reflex game can download the title through Nintendo's WiiWare service for 500 Wii points ($5).

Beyond Muscle March, Nintendo console gamers can also pick up Wahoo Studios' The Amazing Brain Train this week. Available for 600 Wii points ($6), the brain-teaser compilation features 15 different minigames, as well as test, quest, and practice modes. Lastly, Nintendo's Virtual Console revives Sega Genesis side-scrolling actioner Shadow Dancer: The Secret of Shinobi for 800 Wii points ($8).

With Capcom's Dark Void jetpacking onto the Xbox 360, PlayStation 3, and PC this week, Nintendo's portable downloadable lineup is led by Dark Void Zero. Marketed as a long lost Capcom platformer, the faux-throwback features 8-bit visuals and a chip-tune soundtrack. The 500 DSi-point ($5) game tells the story of Rusty, the first human born in the Void.

DSiWare's loaded week also includes Nintendo's Starship Defense for 500 DSi points ($5). A tower defense-style strategy game set in space, Starship Defense includes 30 levels, as well as a variety of enemy types and power-ups. With Chronos Twins DX hitting WiiWare last week, Chronos Twins brings its dual-screen puzzle-platforming to the DSi for 500 points ($5). Gameloft's Me and My Dogs: Friends Forever is also available this week for 800 DSi points ($8).
