Mostly tweaks in this one. A few small tweaks to the Tutorial. Added a few new buffs based on chosen weapon groupings, one for visiting Doris, and a new special buff that may make or break a run. Engine sound now gets a bit of a growl when health is low. Added a backing beat track, doesn't link through to volume settings yet, can be turned on and off in the menu. Slight change to 3D HUD to prepare for future content.
