1. Explore and solve the environmental puzzles
On the whole, Resident Evil Revelations 2 is a pretty linear game with very few branching paths. When you do come across a branching path, however, there are usually more than a few goodies in store for you.
Don’t be in a rush to move on with the story; instead, take your time to explore each room to see if you can scrounge up any green herbs, ammunition, or even parts boxes. Enemies don’t drop items and resources can be pretty scarce, so it’ll be worth your while to search every nook and cranny of the area.
You’ll occasionally come across a few environmental puzzles that require you to step out of your comfort zone and swap over to the secondary character. Get used to it. The rewards are usually worth it. Speaking of secondary characters, that brings me to my next tip.
