Changed boss audio for a test
I added in walking sounds for the spider tank along with a sound we can use for the laser weapon and background fighting noise to make it feel more like a battlefield.

Temp ui
Here are the gun minion, exploding minion and the bosses missile. For some reason I could not get the parents to carry over even though I had the same set up in class.
I broke up each of the minion models, for construction the head always sits on the legs and then the bomb goes under the bomb minion legs and the gun minion turret gets placed under the gun minion legs.
The health pick up is also in the batch.
