SynthwaveZ
A Wave-Based Zombie Survival Shooter Set in an Alternate 1980s Dystopia
SynthwaveZ 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.

All Characters Unlocked
Choose from 5 distinct characters, each available from the start—no unlock walls.
- 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.

About the Developer
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 SynthwaveZ
