Came across a pretty cool dynamic activity just now. Traveled to a random moon and when I got there, I noticed a large Deimos freighter in orbit with a destroyed engine and grav drive. Decided to dock into it and board it, to find that the ship was completely ravaged and taken over by pirates. The gravity system was also on the fritz, causing the ship to fall in and out of Zero-G every few seconds. So you're going from on foot to zero gravity constantly while fighting off a hoard of pirates which was cool af.
There was a locked vault near the front of the ship, and my companion hinted that I'd need to restore power to it. I cleared out the main level but couldn't find anything to get the door open. Kept looking around and noticed there was a broken elevator towards the back of the ship. Looked up and saw that the elevator had a hatch the in the roof that I could open. Opened it, waited for the gravity system to fail, then shot myself through the hatch and up the elevator shaft at zero G. Got me up to the ship's third level where I encountered the main pirate 'boss'. Killed him, then floated through a small corridor which led to a computer room with a computer that unlocked the vault on the ground level. Went back down and gained access to the vault which contained a crapload of loot.
The game really encourages you to go off the beaten path and keep poking around just to discover what's out there. It's this type of stuff that will keep me playing this for a good while.
