Sick of clocks and Sudoku? You might want to liven up your DSiWare collection with this shooter.
Thorium Wars is a futuristic shooter that reminds me of Star Fox if you took out the anthropomorphic animals and stuck it through the generic science-fiction machine. The story takes a backseat for the most part, but it's centered on a future where robots and humans are warring, hence the "Wars" in the title. The gameplay is fun as the controls work well and you have many vehicle types to choose from, and the best part of it all: this sucker is basically a retail DS game in DSiWare clothing.
