Space Abyss is a free, sandbox MMO.

Some standout features are:

Explore a galaxy, landing on planets, exploring and salvaging crashed ships.

Battle monsters and collect resources on planets. Even take over planets!

Build more advanced and larger ships, and build bases on them.

A classless system - swap bodies to meet the needs of what you are doing (Walk around a water planet as an octopus!)

You wake up in a pod, drifting out in space, far in the future from anything you remember. As you explore, you’ll find humans aren’t the only sentient race out here. During your journey, you might even decide to never be a human ever again.

Such is the technology and galaxy of Space Abyss; but some things seem like they can leave. To another galaxy? Maybe one day you’ll find out.
