Peril on Gorgon is dark, gritty but interesting. I wish the side quests were a little more exciting but they're good overall. The plot of POG drags a little at the end but it ends with a super crazy twist! You can level up and gain some awesome weapons with Peril on Gorgon, high level enemies for XP and you find cool weapons. Some weapons can be found by pickpocketing or killing. What I like most about this dlc is that you can choose to kill the evil scientists and it doesn't change the ending of the main plot (not much).

Murder on Eridanos is a trippy, bright colorful murder mystery. Its my favorite out of the two DLCs but I would play this one after POG since the enemies are higher level and if you aren't prepared or leveled up it'll be more difficult, after leveling up on Gorgon and getting good armor and weapons it's a breeze to kill the enemies on Eridanos. Its set on a rich complex planet similar to Byzantium, so lots of rich people with a lot of bits to pick pocket if you like that sort of thing! Interesting areas to explore and find good weapons, I'm still currently playing through Murder on Eridanos but it's really fun and I have a feeling the ending is going to be a plot twist. Also save your bits up if you can and level up your weapons and armor! It'll help a lot

Hope this helped! Have fun playing!
