The escort's war
Keep Britain supplied.
Lead one escort through five dangerous crossings. Protect three named merchant ships with limited charges and imperfect information.
Every ship that arrives matters.
Find the U-boats
Let ASDIC search automatically, read uncertain contacts and close for an attack.
Spend what you have
Depth charges are limited, while escort damage and refits carry across the tour.
02 / THE HUNT
Imperfect information
Hunt what you cannot see.
U-boats stalk beneath the surface. Automatic ASDIC searches the water while torpedoes and sudden contacts force you to react.
- Tap the sea to pull your escort out of formation
- Time a limited depth-charge attack
- Accelerate quiet water and slow down when danger appears
03 / THE CONVOY
Every ship has a name
Every ship matters.
Dawn, Edmonton and Valour are counting on you. A damaged escort and every refit carry forward to the next crossing.
Protect the convoy first.
