Tower of Anvilstein 3D

My first decent FPS, which is modeled on Wolfenstein 3D. It's an arena shooter where you have to kill a lot of enemies and then the boss before moving to the next level. It's primitive, but nevertheless playable.

You play as rookie Friendly Union Combat Knight agent 'MegaJim' who was captured during his recon mission into Castle Anvilstein and imprisoned on the Tower, awaiting possible execution. You have 7 floors of hell to burn through before you escape from Anvilstein alive. Do you have what it takes?
