Swap Ship Shooter (2012) was a prototype made in XNA. In the image above, the pink teddybear-aliens are irrelevant and, but apart from that, the player controls a ship in a top down bullet hell fashion, with the ability to abandon their own ship and take control of an enemy ship instead.

The game would allow the player to be on the lookout for components on enemy ships that were advantageous in the current zone, and even swap out separate parts and not just the entire ship.

The prototype and core concept was very inspired by Cyborg Justice
