Are you playing Metro Exodus and have a character who’s bleeding from every orifice?
Or perhaps you just want to sleep or fix up your gear. The easiest way to do this is to find a safe house. Here’s how to find a safe house in Metro Exodus, in the game’s first open area.
After you’ve left the train, continue along the tracks and then head right down the slope until you see some derailed carriages. Move alongside them until you see a gap at the front of one of them.
Head to this gap and, using the crouch button (X on the Xbox), head inside. Hey presto, all the comforts of home. You can sleep to heal, fix your weapons up or manufacture new ammo.
There are other safe houses to find throughout Metro Exodus, but this should set you on the right track.
