A mass of muscle and teeth lay dormant before you. As you inch your way closer, it comes alive. A sphincter crying for help, beckons you to descend. Your only option is down. Travel through a fleshly vessel, as an eyeball, collecting rheum [eyeball crusties] to grow stronger in your fight against the infection plaguing this.......body. Upgrade your pupils, dodge bullets, and clear the screen of projectiles with cornea crushing blasts!
