Since Angry Birds (an extremely popular bird catapulting game) isn't available on Xbox Live yet, and there is no mention of it being made available any time soon... Indie developers FrozenSoft have taken matters into their own hands and created FishCraft - a very similar alternative.
FishCraft follows a plot in which Fish are fed up with Cats eating their species, so they fight back - and what better way to do so than by firing themselves out of cannons at the offending cats. The gameplay has a few enhancements such as being able to fire all your fish at once and adjust the power of the cannon - however in comparison to Angry Birds it is quite slow. But still... it's about as close to Angry Birds as we are likely to get on the Xbox for the time being.
It will cost you 80MSP and you can get the first episode of FishCraft from the Xbox Live Marketplace link here - marketplace.xbox.com/en-US/Pro...
