Rank 1 = Unlocks the use of Boost Pack <- this one easy to notice
Rank 2 = Boost Pack expends less fuel <- but does it really make much difference. Yeah kind of, but not really.
Rank 3 = Boost Pack regenerates fuel more quickly <- Well yes it does, but no where near enough to make it fun.
Rank 4 = Double Previous Bonuses <- This should correct the lameness of the previous 2 ranks, but sadly was left disappointment.
OK, enough bitching, I FIX
See pics
I tweaked Ranks 2, 3 and 4 to make them BETTER, not overpowered, just better.
Boost Fuel will Drain Slower and Recharge Faster.
You'll actually notice a difference now each time you rank up. Especially at Rank 4.
How high you can go depends on the planets gravity, for example on New Atlantis, you won't be able to sustain flight indefinitely.
But, if you're in low gravity, like on the moon, you'll be able to get really really high, high enough to see the curvature.
It's NOT a Jet-Pack, so don't expect to fly around like the Mandalorian, it's a Boost Pack!
You should 100% be using this command line in your StarfieldCustom.ini
[Boostpack]
bUsePressAndHoldControls=1
It's not required for the mod to work, but the default Boost Pack Bursts are lame, this changes it to a hold down button and use all boost, so much Better.
