Question: Given there's only a few months between this movie and the previous one, that means it's set around 2014 vs. Infinity War being set in 2018, as best anyone can figure. Is there any official word on what the Guardians are up to in the intervening 4 years?
Answer: They're mercenaries, like we see with the Sovereign. They do good things for money. We see this with the Sovereign, and Quill's comments make this seem like this is normal. Later, Rocket makes a comment about raising their prices. In Infinity War, they only respond to the Asgardian distress call because they expect to be paid.
Chosen answer: Short answer: Probably nothing much good. In all that time Quinn still felt like a reaver, and Rocket doesn't deny he likes crime. Only Gamora keeps them at bay from doing anything really nasty. In the mean time they try to do good things, protect planets, hunt pirates, stuff like that. It's a crazy bunch of individuals.
