The corner of your screen shows the sub in section. It tells you what the crew is doing and what is happening in every compartment.
Compartments
- Drive — The propeller shaft and its drive
- Engine — The engine room
- Reactor — The reactor and its cooling
- Control — The helm and the periscope; the only way up into the sail
- Quarters — Where the crew rests
- Sonar — The sonar station
Crew: REYES (captain), OKAFOR (engineer), LIND (mechanic), MAEDA (sonar operator). The dots show where each of them usually stands.
Crew
| Name | Post | Usually |
|---|---|---|
| REYES | Captain · CPT | At the helm, on the periscope, plotting the course |
| OKAFOR | Engineer · ENG | In the engine room, checking the shaft |
| LIND | Mechanic · MEC | At the reactor, fixing pipes, greasing the shaft |
| MAEDA | Sonar operator · SON | On the sonar |
While all is well, each of them gets on with their own job: working, walking around the boat, chatting, sleeping. When something breaks, they all run to it.
Damage
A torpedo hit or a heavy ram can damage a compartment, set it on fire or breach the hull there:
| Hit | Compartment damaged | Fire | Breach |
|---|---|---|---|
| Gun | 5% | 2% | 3% |
| Heavy ram | 40% | 10% | 20% |
| Torpedo | 70% | 40% | 30% |
Below crush depth the compartments start to give way too: a breach opens with a 10% chance every second.
Fire
A fire grows by itself and takes hull every second: up to 4 a second at full blaze. After 10 s of burning the compartment is damaged, and after as long again it goes offline. A big fire can spread to the compartments next to it. The more crew fight it, the faster it goes out.
Flooding
A breached compartment takes on water. Once it is more than 90% full, the water spreads to its neighbours. The crew seals a breach in 7 s and pumps the water out. A fully flooded sub sinks at 7 studs/s.
Repairs
A damaged compartment takes 8 s to fix. One that has gone offline takes 14 s.
