ZooM
From ZDoom Wiki
ZooM is a racing mod for ZDoom, but rather than driving a vehicle all races are done on foot. Many items have been added using DECORATE, including 5 flavors of sphere. Several maps have been completed by various authors, including NiGHTMARE, 5hfifty, and Espi. The project is co-lead by SargeBaldy, who conceived the idea, and Nanami, who does all the coding work.
The Story
Once upon a time you were a space marine. You were the best damn track star on earth. You ran in the Olympics in both 2005, 2008, and 20009 and won so many medals combined some people started to call you Mr. T. Your toilet was getting stinky so you flushed it. You meet the girl of your dreams 3 days later and her name is Sally. You get married and live happily ever after.
But then, something happened. Your house caught on fire! Pulling out a fire extinguisher you manage to kill the flames before they destroy your pet olingo Sally.
Eight years later, you get sucked into a reality warp bubble.
"Nooooooooooooooooooooooo!" you scream. Suddenly, you are in a lounge. A lounge full of weird stuff and grapefruit. Grapefruit. You know it best as Citrus paradisi but are aware the name was changed to Citrus X paradisi. But you've never understood why.. perhaps this place holds greater secrets than you imagined. You gasp as past the pile of grapefruits you see track runners. Track runners who are good. Maybe even more gooder than you. More... more gooder... You know what you have to do. You have to walk through a reality door into many separate individual dimensions and kill them, kill them all. You must. If you don't, you'll never get home. You'll never get back. To your home. Ever.
