That's a good one. The 24 pax were on sale at the local store here the other night, advertised as "Get 24 for the price of 18 when you buy two 24 packs of BrandX brewskeez!!!"
As for that UpgradePack, it is a combination of files listed in the SubName.upc file, to "upgrade" your equipment, such as the radar or sonar or deck gun, etc. The "ladder" would have to be "disguised" as equipment though... but the sub's flag can be done with an entry in the SubName.eqp file... so if it works for an exterior node, surely it would work for an interior node, right?...

- although, we do know how everything in the game is so "the same", yet so different... Of course, then we should be able to make the broom appear also... hmm.
