Last Refuge

Out of nowhere, warning sirens have started. No one knows what's happening. Outside, panic and chaos have broken out but the only thing that concerns you at this moment is how to get to the nearest atomic shelter with your friends as quickly as possible. You are in luck, there is a bunker right next to you. You enter it thinking you're safe from the worst. But as soon as you're inside, you discover the bunker has seen better days - it's without electricity, water and worst of all, there's only enough oxygen for 60 minutes. The only thing you can do is to get the bunker up and running so you can survive the apocalypse. Your first task: start the backup generator. Your second task: turn on the main water supply. Your final task: activate the main oxygen supply. You have a plan, but can you do it all in 60 minutes? Your task isn't to escape. It's to survive!
