As of now, there is only one free game named to be part of the promo for Xbox Games with Gold service.

According to Christian Today, they normally announce the full line up of games around the 25th of the month. It's just a trend, Microsoft doesn't do it out of protocol, they don't announce their routines in terms of releasing promos. If ever that's the case, people would just have to wait a little longer to find out the games that will be part of the promo.

"Zheros" is a less complicated "beat 'em up" game that makes gamers fight through a horde of enemies just to advance through the game. There is no hiding or spying. In this game, players would just have to be as aggressive as they can be to be successful.

The game offers single and multi-player modes according to We Got This Covered. The game was released on January 16 for Xbox One and would be available for the promo until February 15.

Rimlight has described their game and it read as follows:

"In a journey through distant and unknown galaxies, you will play as the members of the Zheros squad: Mike and Captain Dorian. Brave, strong as awkward and dim-witted the first one; agile, smart and ready for anything the second one."

For those Xbox One gamers out there, you guys should not miss out on this once in a lifetime chance. Gamers can have this incredible game with no charge whatsoever for a whole month all thanks to Games with Gold.
