First there was the coughing, then the fungal infections, and by the time the captain had decided it was time to abandon ship, it was almost too late. More than half the crew had already been infected.
There’s no way any port will allow your ship to dock.
The only way out, then, is via the escape pods.
Except that without extra battery, the escape pods will only go so far—definitely not far enough to reach the nearest planet.
Your aim is simple: go through the remainder of the ship to extract batteries from every device and machine left working, all to get enough energy to power your escape pod to go the further amongst the survivors.
But beware. Your fallen crewmates are roaming the ship, and in their hazy state, will attack you upon sight. Avoid them at all costs, and if found, use your torchlight to blind them.
