This system creates the need for audiovisual cues to help the player.
- Various engine sounds. Different engines should sound differently.
- (Possibly) alternative hyperspace sounds. Hyperspace sounds consist of five phases: engine chargeup, engine powerdown, constant engine hum, jump in, jump out. See snd/sounds/hyperspace_powerup.ogg, snd/sounds/hyperspace_powerdown.ogg, snd/sounds/hyperspace_engine.ogg, snd/sounds/hyperspace_powerupjump.ogg, snd/sounds/hyperspace_jump.ogg.
- Weapon and explosion sounds: pew pew whoosh crash boom bam bling.
Nothing specific at the moment, but more is always better.
