It is almost invincible, the only thing that can bring her down are the large ships. I'm not sure about depth charges, the enemy wasn't really around long enough to use them on me. There is a mission Rockin Robbins made called the Convoy from Hell, very fun mission with this sub, only recieved 7% hull damage after I had sunk all the ships.

Hmmm, but does it need to ABSOLUTELY be used with FORS? I'd like to use it with my stock SH4.

The sub, no, the sub is compatible with stock, FOTRS, TMO, and RFB. Only the mission is compatible with FOTRS because it uses german ships that can only be found with that super mod.

Good. So it means I can run a stock mission with it right?

Yes. The sub only modifies two files and those do not affect the missions at all.

Good so I'll test it tonight!

Ok so after testings, and I know it's just a beta, I realized that it can dive but... it's not moving while diving or underwater like... at all! Will you fix this?

Ah, now here in lies the fact that it's the size of a battle ship which means it's slow to accelerate. At 1/3 throttle the ship seems like it doesn't move at all but it will get up to speed in due time. Also, in order to dive the ship must be going 10 knots or above, if not it kind of just sits there with the stern of the ship in air for quite a bit.

No I mean I ordered the dive while at flank speed. It started to dive ok but like 20 seconds after the dive order, the engines (still at flank) dropped at 0kts. She dived 400 feets below on horizontal position still at 0kts. When I ordered to surface, she came back up on horizontal position just like she did when diving. I really can't understand what happened. :hmmm:

Hmm that's interesting, I'm not sure what could be causing the problem. You're using the original download right and not installing the TMO or RFB pack. That could cause a problem. Also make sure that the upc file in the Silent Hunter Wolves of the Pacific\Mods\Titan\data\UPCData\UPCUnitsData folder, the number in the file name should put it at the end of the list. I've had some weird things happen when two ships have the same number in the file.

Oh wow this thing is really something.

But I don't understand why the guns have such a short range. I was getting pelted by destroyers and other ships, and my main guns remained silent. I did not understand why this was the case. Finally the guns let loose, and made the attacker disappear.

Had the same thing with the game patched to 1.4, I think 1.5 is needed...

I'm patched to the last version available. After all, I did buy SH4 on STEAM. STEAM updates every game you buy automatically so you can say I'm running it on 1.5. The problem comes from somewhere else.

dear god, it's the M class sub on steriods!

Yes v1.5 is needed to run this boat. Do you also have the U-boat missions pack? I don't see why that would have anything to do with the sub not functioning correctly but sometimes those expansions change things around for all the subs. I'm not sure what else the problem could be because I've driven the sub countless times, dived and surfaced used all torpedoes and such and never had the engines just stop. It's hard to fix a problem like this if I can't replicate it.
