Gods Will Fall

I've done two playthrough videos that you may find helpful.

One is focused on achievement completion and is broken into 10 parts, one per God, with commentary:

The other is a single segment no item run (no commentary):

If you're not a god slayer yet, but simply want to complete the game, use 'delete from console/restore from cloud' save method.

Start a new game, as soon as can control your characters quit the game to Xbox dashboard and let the save to be uploaded to cloud storage (I assume you have internet connection). Go back to the game.
Start figuring out dungeons, if you find the one you've entered being too difficult at this stage, or your character is killed, simply delete your save from the console and let it be restored from cloud once you launch the game again.

Every time you beat a boss, collect the loot and distribute the weapons, and then quit the game completely, so a new save is uploaded to cloud.

Carry on like that until you beat all 10 bosses
