If you want each level of tower defense game to be full of surprises and changes instead of just brain burning calculation, Oasis Defense is the game you are looking for. Here, every game is a journey to choose the path of evolution.

Oasis Defense is a minimalist tower defense game. It is very easy to start. You will plant trees to fight against the ghost army, and choose your own evolutionary path among the random gained rewards to protect your oasis.

The arrangement of trees has a high degree of freedom. You can fully use your artistic talent, but at the same time, you should pay attention to that all trees will be attacked by the enemy, so the defensive formation is very important. You should carefully protect the fragile resource trees and let the high damage trees have good positions.

After defeating each wave of enemies, you will get random evolution options and make choices from them. Therefore, this is not a game that can be calculated accurately in advance. Players need to adjust their evolution routes and array strategies according to the situation.

If you’re thinking about buying Oasis Defense please keep in mind that this is a game developed independently by a game lover. I just hope this game can bring a tower defense experience with more surprises and changes to the players.

Please don’t hesitate to contact us if you have feedback, questions, or problems with the game. We’ll do our best to get back to you as quickly as possible and provide support if needed. Also let me know if you enjoyed the game, that means much to me!

This game will bring you:

  • Tower defense experience is very easy to start. Even if you haven’t played tower defense game before, you can start it easily.
  • Simple and clean graphic style.
  • 40 carefully designed levels, each of which contains normal mode and endless mode.

Oasis Defense is inspired by amazing games like:

Thank you for playing and your support!

How to activate Oasis Key

Sometimes a Steam Digital Code requires an EU IP-Address in order to be activated on Steam. Read the store’s description if it’s only required for activation or if you also need an EU IP-Address in order to play Oasis CD key. If you don’t know how to do this, most stores offer help or a tutorial.

Activate the Steam Digital CD Key Code on the Steam Client. Log in and look at the left bottom corner and click on “Add a Game…” and then on “Activate a product on Steam”. Put in the code for Oasis CD key and have it in your Steam library, ready for download! You can install Steam to activate your Oasis key

Steam Keys are intended as a useful tool for game developers to sell their game in other online stores and retail. Steam Keys can be activated by customers on Steam to license Oasis. Valve offers the same free bandwidth and services to customers who activate a Steam Key as to customers who purchase a license directly on Steam.

Many sellers are wholesalers who buy game keys in bulk directly from the developers and publishers. Because they buy a large number of products at once, they buy them at much lower prices. This in turn allows them to offer their customers attractive discounts.

A Oasis key for the Steam-Client does not expire and after activation Oasis can be downloaded and played forever. This also applies to all other clients.

Often games that are playable on Steam are also available on: Rockstar Games, Epic Games Store, EA, Humble Bundle, Windows 10, Gog.com, Xbox Play Anywhere, Battle.net, UPlay and Amazon. Make sure to check all offers and that you are buying a Helldivers 2 Key for the right Client.

EMEA stands for European and Middle East or Africa, and a several other countries. Read the store’s description to see which countries are allowed to activate the Steam Oasis CD Key, or you can use a VPN (Virtual Private Network).

You receive a gift on your Steam account. You have to accept this Steam gift so Oasis can be added to your Steam library and ready for download. Read the store’s description if there are any region restrictions. A Oasis Steam gift is not a Oasis Steam CD Key.
