So the Nazi's found a secret ancient tomb of technology, but an old guy managed to splice in a mould into the 'super concrete' they found in the tomb, which has been key to their growth - but also means their buildings are falling apart and some even collapsing. So we go find him for some reason that isn't entirely clear (the VO is sooo quite), and he says there is a bigger tomb under the sea (because why the fuck not?
). So you go steal a u-boat to get to the tomb (no obvious reason why we are doing this? - other than to get unspecified technology?).. You do this by hiding in a torpedo - to get to the torpedo, you drive a mini-sub about 10m in the sewers and somehow arrive at an underground train station that happens to have a train that is carrying torpedos. You drive the train to another station and get into a torpedo. When you wake up on the u-boat, by luck it is the largest u-boat the Nazi's have and it even has a nuclear capable main gun, but unfortunately the captain gets killed - so for some reason we absolutely need his nuke codes (to blow up a building?) so the only way to get them is to go to the moon. In order to do that, you have to hijack a train on a bridge and capture the cheif scientist that we somehow know is on the train - and that'll let you get the moon somehow. So in order to stop the train you use a giant levitating sphere that shoots grappling hooks, which was the only useful thing in the underwater vault... And that's about as far as I am.. WTF?
