Zet Zillions is a story-driven roguelike deckbuilder where you will navigate through vast space maps with Foam Gun and her planet-ship Baby Violence, in search of a new home for humanity. Create chaos with the unique fusion system, with more than 100 possible combinations to discover. Overpopulate planets (by throwing your own crew at them) and blow them into smithereens!
INTO THE FRAY!
With easy onboarding and engaging mechanics, Zet Zillions wastes no time throwing you into action. Think ten steps ahead, strategize carefully but boldly, and find the best tactical approach to defeat COLOSSAL enemies.
COMBINE (almost) EVERYTHING
Build not one, but many mega decks and strategies on-the-go. Master the fusion system to combine your cards, revealing new, spectacular effects…. Or embarrassing bluffs. There are more than 100 combinations available, and some may not go as well as others. Hey, no risk no glory, amirite?
A UNIVERSE FOR YOU TO EXPLODE... err, EXPLORE
Traverse randomly generated galaxies and visit thrilling locations. Scavenge abandoned shuttles, discover hidden portals, and meet tons of characters while embarking on side quests. Oh, and don’t forget to make good use of your pineapples.
…Pineapples, yes. Why that face?
DO YOU REMEMBER WOLFSTRIDE
Wolfstride is one of the “best games from 20xx” you missed, “hidden gems you need to play before you die” and all that. It is also the previous game by Ota Imon, the studio behind Zet Zillions.
You don't need to play Wolfstride to enjoy Zet Zillions, but if you want extra credit* (and extra FUN), we recommend you give it a try, as you'll learn more about Zet Zillion's universe.
*Credit can be redeemed on our social media, where we will compliment you and tell you that you are very cool.

Monthly Recap – June Edition
We are already at the end of the second quarter for the year and the summer is already giving us so many updates and cool information on a lot of gaming titles and events. We tried our best to gather some of the more exciting pieces, although it is quite difficult to contain everything in just one single post as there is simply so much to talk of. We kick-off things with as many of the highlights from one of the most important gaming events of the year…
The summer heat is already upon us and the rising temperatures are coming ahead, but here at YUPLAY prices are going in the opposite direction and are dropping down like mad!
