v1.7 - September 2017

Here are the new features in Xemo v 1.7. We've received an overwhelming
response to Xemo after moving to Free-To-Play. New: The Evolution Chamber, Leaderboards, in-game tutorial videos. If you are having trouble getting started, check out our videos at https://www.vimeo.com/xemory.   Oh yeah, we added a Linux version, tested to run on Ubuntu 14.04 64bit.

v1.6 - August 2017

This is a major overhaul of the user interface, robot designs and game levels. We have completely re-designed and replaced the game levels with 16 new levels - from mostly easy to more difficult. We've reworked the user interface, created better controls including keyboard mapping for motions. The game has been split into sections: the Robot Selection, the Motion Creation and the Level Play section. Have a look at the new screen shots - the game art and new robot designs are impressive!

v1.4 - May 2017

  • Revised tutorials (easier to follow).
  • Re-designed game levels 1-5

v1.3 - April 2017

  • Added three new robots (4 legged) to the game (see screen shots)
  • New hotkey binding for motions for more interactive game play.
  • Updated user interface and transitions between the robot lab and challenge floor.
  • Demo now has Gravity Well and Hot Key motions turned on.
