O.A.S.I.S.
O.A.S.I.S. is a fast-paced, arcade-style zombie survival shooter set in a gritty, alternate 1980s world. Designed as a break from competitive multiplayer fatigue, this game lets you and up to 3 friends team up (or play solo) to fight off relentless waves of the un-dead.
With each wave, the intensity rises—zombies become faster, tougher, and more aggressive, pushing you to adapt your weapons, tactics, and teamwork to survive.
- 🧟♂️ What Makes O.A.S.I.S. Different?
💥 Over-the-Top Action
🎮 Gameplay That Respects Your Time
🧩 More Than Just Survival
👤 All Characters Unlocked
- Airstrikes: Multiple airstrikes to use and find on the map!
- Drop Pods: Call in drop pods to resupply, bring heavy ordinance, auto turrets and much more. Don't get caught un-prepared and empty handed against the horde.
- Perks system: buy perks from different points around the map to gain special abilities. There are 6 perks at the moment and more will be added over time.
- Traps are placed at various locations through out each map to help you tame the undead horde. Each trap is unique both visually and how they work. Some are devastating but quick, Others are meant to slow the horde down and help you make a quick getaway.
🔫 Features
All major updates, new maps, weapons, and content will be free for everyone who owns the game.
Hi, I'm a solo indie dev who works full-time as a mechanic. I built O.A.S.I.S. to be the kind of game I’d want to play with my friends—something fun, fast, and full of personality.
There’s no grind. No complicated systems. No pressure. Just good, chaotic, zombie-blasting fun.
Your feedback matters—I take all suggestions seriously and do my best to respond quickly (when my wife and daughter let me!). Updates might not always be lightning-fast, but I'm constantly working to improve the game.
Thanks for checking out O.A.S.I.S. Join the Shadow Games Discord for news, suggestions, and community fun!
