Fort Zombie - Solo Hard Finale (No-hit, No Traps) & Ending 2
1This is gameplay from "Fort Zombie" v1.0.7, showing the final battle from the Hard-difficulty playthrough.
My character is a Soldier defending a School all by himself. I noticed the zombies can't climb up the tables in school's cafeteria (unless they glitch eachother into the table or up in the air), so I exploited that to hack the whole horde to pieces with a Machete. I kept an eye out for armed zombies and quickly swapped to M4 to eliminate them before they could shoot me. It took a few tries, but I managed to eliminate the entire horde without taking any damage. :)
The game considers the battle to be a "Costly Victory" as there were no NPC survivors at the end, so the game thinks everyone else died. Apparently, the developers never thought there'll be anyone crazy enough to try to solo the whole game. XD
