I wonder if we really only have two engines

[Ducimus]

Ive had this hunch for awhile, and this kind of supports it.

You know all those post about only have 2 engines destroyed but being unable to move?

Well, ive always thought, it was because we *really* only have two engines. Or so has been my hunch. Since the game is based off of Sh3, and in SH3, subs only had two main engines, not four.

So, if you look closely at a subs UPC file, heres what you'll find:

So it looks like, engines number 3, and 4, arent tied into any damage zone. Do they really do anything? I don't know, but i kinda doubt that they do.And from behavior observed where if you lose the number 1 and 2 engines you end up being dead in the water.... this would explain alot. Could it be that engines 3 and 4, are purely just for looks?
