Tutorial time!!
So for those poor souls who are wondering what to download(android only) compressed or the zip file then I would recommend the zip file cuz it's pretty easy and the instructions on how to download it is pretty easy
First you would need to have zarchiver or any other apks that could open zips
Then install eternum the 50mb app after that open the app allow the storage permission exit the app open the zip again
And then copy the Eternum file the 2.40 gb one
After that go to documents/Ixalon/com.caribdis.eternum/game and then paste the file here
That's all hope it helps!
