About This Game

(DISCLAIMER! The upcoming March release is the release to Early access, With the first level. The full release will come at a later date. New maps will be released slowly) All music by Karl Casey @whitebataudio on YouTube.

O.A.S.I.S is a simple wave-based zombie survival shooter that combines the best elements of classic arcade-style shooters with the atmosphere of an alternate 80’s dystopian world.

Designed to give you and you’re friends a break from online competitive shooters. You must fight off hordes of the undead as they relentlessly pursue you through the Levels. With each passing wave, the zombies become stronger and more dangerous, forcing you to constantly adapt your strategies and weapons to stay alive.

So what makes O.A.S.I.S any different from some plain "Zombies mode"?

INSANE ACTION! want airstrikes? Yup go ahead! Need a personal Defense and Emotional Support Companion bot? The P.D.E.S.C is there to help! Out of ammo? All good, Go ahead and call in that emergency supply drop! Those and Many more features to come!

– No grinding for unlocks! Everything is in-level – whether you find it and purchase it with points or get lucky and grab it out of the random loot box – making every single play-through different. The only thing unlocked through playing is a simple rank to show off to you’re friends.

– Play the levels infinitely or complete the puzzles to call a final boss and win the level.

– In-level puzzles that unlock secret rooms, hidden weapons, and Easter eggs.

– 4 playable characters all unlocked from the start.

– 4 playable maps: Death Valley, The Farm, Downtown, and The Coliseum. (More Coming Soon)

– Tons of weapons! Including melee weapons! Every single base weapon has multiple variations with they’re own unique attachments, tier, recoil, fire rate, sounds and damage. The more you discover, the better weapons you will gain. (More base weapons will be added over time)

– Airstrikes: Multiple airstrikes to use and find on the map!

So far there are 4 airstrikes bound to a character and 2 that can be found in level utilizing a flare gun. But be careful…friendly fire is on! (More airstrikes will be added over time)

– 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.

– Play single player or online co-op with up to 3 friends

– No paid DLC: All major updates, add-ons, and levels will be free if you purchased the game.

– There are many features, addons, revamps, modes, That I have planned for the future. Also join please join the Shadow Games discord for all news, suggestions and more.

About the developer:

First and foremost I do not consider my self a real "developer." Every single prop/animation was purchased on the Unreal Marketplace as well as quite a bit of the blueprints (code). While I did write a lot of code/blueprints myself, I didn’t create all of this from scratch. I’m just one guy who wanted to create something fun to play with my friends. I wanted to make it the game I want to play with levels and weapons that I love. That being said, I do take feedback seriously and will try my best to to fix any bugs, take suggestions, or change basic game mechanics. At the end of the day, this game is meant to just be fun. No grinding. Not overly complicated. Not stressful. Just good, laughable, simple, fun.

I work a full 40+ hour week as a mechanic but spend most of my free time working on this game, mostly to the chagrin of my wife and daughter. If I don’t get back to you quickly on Discord or updates aren’t as fast as hoped, know that I am working as fast as I can and will get back to you as soon as possible. This project means a lot to me and I hope you enjoy playing it as much as I do.
