Better Wingsuit Boost
--Longer Lasting Boost - This is not technically infinite, but the drain is significantly reduced, changed from a factor of 5 to 10000. With this, you'll still be able to fly from one end of the map to the other, so that infinite feel is still there. This also cuts off the boost immediately after letting go of the key, so you wont have to open your parachute or disable the cheat in order to stop boosting.
--No Boost Cooldown
Unlock Grappling Hook Mods - This will let you unlock any grapple mods without having the required number of gears.
