Bump...
I just spent the last 2 days going over SH4 Shake Effects from Bombs, Depth Charges and Torpedo Impacts.
The MODs I had made the boat rock and shake for any explosion within 800 meters and that includes ships exploding as they are sinking. The sinking ship explosion/shake really startled me.
Another thing I noticed while playing in SH4 was that SH5
REALLY needs a EAX Sound MOD. Explosions really sound like explosions with a long trailing rumble and secondary explosions have the same effect. That and a good shake of the Sub was very impressive. The current explosion sound samples and other effects in SH5 are very depressing.
