When blowing all your cash on a yacht just isn't enough
The price isn't bad, in line with most of the supercars. It has some neat toys and upgrades, plus missions and a heist, but like most of this sort of stuff in GTAO I'll pass on the submarine I'm sure. The new submersible is cool.
The one thing that does appeal to me is the helicopter. I just love flying helicopters in GTA. The flight model sucks and it's far from realistic, but I have so much fun flying around Los Santos. This sub can carry a new helo, called the Sparrow. You can buy it from Warstock, so don't need the sub to get it, it seems.
I have a hangar at LSIA and it's stuffed with helicopters. But there's room for another. There's also a Sea Sparrow with pontoons.
These sorts of updates rarely have much in them for me, but new content is always welcomed. And from what I hear, the heist is soloable. That might be worth buying the sub right there. Getting competent heist crews together has been my problem since I started.
