#117 Final Audio

EffectSystem

Merge remote-tracking branch 'origin/master' into boss_meshes

Conflicts:
Laser and shot gun meshes are here make sure there up there
Fixed the LaserGun
Drop Points
work on #146
- You can now provide the initial state a list of potential drop points and it will pick the one closest to the player. This is done so the player can always see the boss when it drops down.
Impact Particles
work on #146
- Added a visual effect for when the boss lands. It's pretty sick.
Rotate Spider Tank
- Updated the rotation of the local spider tank mesh now that the fbx has been fixed.
