It’s A War Out There 1

Caleb has been hiding out in his cabin for a long time, getting increasingly bored, but weary of all the dangers that lay beyond. After all "it's a war out there". Eventually however, the protagonist decides to venture outward, figuring that all those things that seek to hurt him he can hurt in return, and thereby find his means to amuse himself. The level features cemetery, urban, library, sewer, water, and cave areas and even a laboratory with portals to both the frozen north and to a temple complex. It is here that the player meets his final challenge: two beasts that guard the exit.
