Keep an Eye on Gas and Blade Durability
One of the aspects of Attack on Titan’s gameplay that will take the most getting used to is resource management. You use gas to move about the world quickly, and your blades become dull over time as you use them. Thankfully, you can swap out empty gas canisters and dull blades, but you have to keep an eye on their meters to know exactly when to do so.
You can find both meters on the lower, left-hand corner of your screen. Next to your characters icon you can find a blue meter, and a segmented gray meter. The blue meter represents your gas, and the other represents your blades. Once you see them hit the red, it’s a good time to find some cover and swap them out. Keep in mind that you’re completely vulnerable when doing so, and the action can’t be cancelled once you begin.
