13 Days in Hell is a vivid 2D first-person shooter that controls a chosen character and must survive an invasion of hell spirits for 13 days. Good luck!
The souls in hell will try to stalk and murder you with axes in hand, so be careful what you do. Your aim is to stop the zombie creeps from annihilating you by destroying each and every one of them. The zombie's attack in waves, and your mission is to stay still and kill the zombies before they reach you. If your HP bar runs out, the game is over. You have to restart the game.
There are 13 days in all, and each day represents one of them. Once you've completed one stage, you'll be able to go on to the next and unlock new weaponry along the way. You can only use a handgun on the first day, a desert eagle on the second day, and so on. The most important thing to remember is to aim accurately; otherwise, you will run out of ammunition and be in serious trouble.
Every day, use the souls you've slain as currency to purchase improved weaponry. These weapons are extremely helpful because stronger souls with various patterns will chase you every day.
Have a great time with 13 Days In Hell!
