Abadox: The Deadly Inner War

Background

Abadox is a futuristic space shooter that uses both side-view and top-down perspectives. As the last remaining captain of the fleet, your goal is to fly into a monster and destroy it from the inside. Hindering your task are captured spaceships, parasitic worms, and even cells from the monster's immune system. The boss you encounter in the first level is a semi-digested dog, which conveys a certain amount of revulsion not easily achievable on the system.

Gameplay

You'll have to shoot your way through the bowels of the monster with everything you have and more. You can find defender blocks that will help you avoid some attacks, and be thankful for that, because one hit, and you're finished in this game. You can also find upgrades for your gun, which you'll desperately need as well.
