4.6/5 (54 votes)


All of your nightmares pales in comparison to space leviathans who eat whole planets! But, of course, this is what you're forced to face in 8Bit Skull's action adventure title, Zos. It's been thousands of years, and the great monster, X'o'chthu,is back for another round of celestial chomping. It is up to you to gather the lost essences of heroes-past and use their powers to fight it off once again.

Cool game! Not too long, not too short, nice to finish in a few hours. One thing I noticed, I just guessed one of the potions which messed up the order of things. Might leave you frustrated, but the game works out anyway, just keep following Master Movo's lead :-)

Oh, one question remains for me:

On your home planet Rhisla there are some faint signs on the far left of the dig site. You can show these signs with a Reveal potion. What are these for? Are these the ones used to unlock the first temple? Can't remember ;-)

Found a bug: When I

drink the health potion, my fire potion disappears, so I cannot finish the first boss.

Firefox, latest update of flash, etc. Ideas? I'd rather not have to clear the cache and start over if I can avoid it. Thanks!

I did try that, but I no longer have the fire potion to use. I tried to equip it from my inventory as well.

Found another bug...

After learning the fortify jump potion I went back to my starting place and picked up the health upgrade there...and got the achievement for gathering all health upgrades, instead of the one for picking up *a* health upgrade.

Great game :D

What are those secret characters that apear :D Only found the one that slayed Murmur and the one the Heals you :o Is it from previous games meybe ?


There is one red demon that claims he has killed MurMur and gives you MurMur's blood(3 health potions) . He is on the planet in war, On the Far Left side of the map.

There is One guy that heals you :D And claims to be a doctor. He is where the old man dies inside the beast mouth, top of the room. Just go up with the flying potion

@Kyh, thanks, thought so indeed, although I was silently hoping those were for a secret yet to be uncovered by me ;)

Good game! Does anyone know how to get the achievement "Fourth Wall" (visit the developers)?

Hmm. I'm missing something on Aeryl, though I'm not sure what. I've gotten the

zero G and jump potions, but Movo keeps telling me to improve my jump. He's told me to try to mix in sparkberries or something, but I can't find those. I haven't found the elixer there yet...


Any tips?

I have emailed an updated game file to JayIsGames which should fix the achievement bugs highlighted in the comments.


Elaris, as far right as you can go, gravity potion over the wall.

silent george:
Movo is telling you about the Fortify Speed potion. It is a non-essential potion, i.e. not required to complete the game.

What you need to do is return to the beginning of Aeryl and use a gravity potion to float up into the temple.

Thanks, Alex. I got the Fortify Speed potion, but previously I was just

floating around the sides of the temple, hadn't tried to go through the middle.

Thank you, Alex! I haven't even got that far, I just thought I had to visit the developer's website and was wondering why it didn't work.

OK, what am I missing? I've gotten six of the essences, visited my friend Movo in the belly of the beast, but I can't find any X'o'cthu to fight, just some minor league baddies. Where is the world-eater?

Thanks, Kyh, a perfect clue.

I think this game deserves the "metroidvania" tag, one of my favorite tags.

I believe I found an exploit. Relatively useful:

After creating and drinking two Fortify Health potions (at the station where the recipe is) I picked the last heart at the tech planet. If memory serves one of the potions ended midway, but the other was still in effect at the pick up time.

It seems as if my maximum health is frozen, which is interesting, to say the least.

Great game but

I want to find all the health upgrades. I got the onee on Rhisla, Mezlta, and Elaris. I found Mormax on Potal too. How many upgrades am I looking for? Is it one for each planet?


Indeed - one per planet, 7 upgrades to make a total of 10 health points.

I'm trying to find the

health upgrades on the last 3 worlds but i can't find them

found a glitch.

you can knock the flying sentinel orb robot guard out of the level in the tower on Elaris, on all floors in the tower. use a fire potion when he is in the first left upper corner of the room (where it hibernates, actually), you can lure him there because he does not get low enough for the next chamber to follow you. Slap him with a potion that will not instantly kill it. you see it in the black region surrounding the level now - the space which you can not access.
