Resting comes in threes.
When the shit hits the fan and you need a moment to regroup, a Lockdown is your best bet. Find a secure location, barricade the doors, and take a deep breath. This is your chance to assess the situation take a bunker break and patch up any wounds, reload and repair your gear. You will not want the place on alert when you bunker down, but if you can find a quiet corner of the complex, or you have neutralized the local threats, looped the comms and cameras, you might just be able to snatch a clean hour of miserable peace, long enough to stop bleeding, swap out ruined hardware, and swear at the ceiling about every poor life choice that got you here.
In the depths of a Blackout, all systems are down, and the only light comes from the faint glow of emergency indicators and the flare of the welding unit as the tech grunt tries to repair your shattered equipment. It's crucial to stay calm and hidden. Use this time to catch your breath, assess your injuries, put people in body bags for extraction later (yea right) and plan your next move. Remember, the secrecy is your only ally now. Typically lasting 6–8 hours going dark allows for Heavy repairs, software updates, weapon calibrations, and medical treatments that take time. this allows for deeper healing and system overhauls and repairs and planning.
At least one squad member (or automated system) should be monitoring perimeter/security when you rest; otherwise, there’s a chance of intrusion, ambush, sabotage, or waking to a nightmare of an alien eating the last of your squad mates, if you just shut your eyes and hope the void doesn’t eat you. You wont wake up. Fleshies are yummy.
