Aeon Rivals — Free-to-Play 2D MMO!

Welcome to Aeon Rivals, a free 2D side-scroller MMO for Windows and Mac. Team up with friends, select from an expanding cast of characters and duke it out against invading Celestian monsters. You’ll have to stay on guard if you want to take these beasts down!


Celestians are invading Earth2, the home planet of many innocent lifeforms. As a member of the Aeon Rivals, your job is to stop the destruction of Earth2 before the damages become irreparable.

While Aeon Rivals is a 100% free 2D MMO, we have a strong stance against pay-to-win schemes. All our extra features offered will never give players unfair gameplay advantages. Our goal is to keep the playing field as level as possible so it stays skill-based and enjoyable for everyone.

Update [1.8.8]

1.8.8

General

It’s Aeon Rival’s 4th anniversary! We’re celebrating with a new update that includes party hats, a new Natural Gift for KeRobo, big performance improvements and cake!

For the rest of this week all Club Aeon memberships are on sale, too. Just use checkout code LETSPARTY to receive a discount at checkout.

While delving into bug fixes for the previous Egg Quest event, I noticed a design problem with how event data and scoring is read in and cleared every month. I rewrote a portion of the code to help iron out issues. I’ve also made a few adjustments to gameplay in this release.

I was working with some GPU code and I implemented a couple of big performance boosters. You may even feel a difference in your FPS!

4th Anniversary

Players can now wear party hats with Flavor “Celebrate”. The Victory Cafe is also serving cake that gives some pretty useful stat boosts. More info »

Check the changelog below for a list of changes.

Update [1.8.7]

1.8.7

General

Happy Spring. Thanks to everyone who participated in the Lucky 7 event. This update introduces the all new Egg Quest event and also introduces a brand new V-Keys system, bug fixes and more improvements.

Egg Quest

Hunt for eggs hidden around town! The local Beasts are attracted to them and steal (or even eat) them, so you’ll probably need to defeat Beasts to find the eggs. The X-Bulletin is rewarding Wake-Up Emitters and Acolyte Beast Eggs as rewards more than usual this month, too. More info »
