Survival Game

Has 3 guns and 3 upgrades (discussed in main menu).

First gun (some sort of laser pistol) uses raycasting for firing, other two (heavy and sniper) uses actual bullets with collisions. Other two also have ammo that can be upgraded (max number of bullets and reload speed!), and their own reload animation.

Just for brag-worthiness: guns can be dropped with Q and picked back up. 

Also for brag-worthiness: there's an inventory system by pressing i
All potions picked up will be shown in the hotbar, but also in here. You can also drop the potions by clicking on the "x" when a potion is in your inventory, or use it by clicking on it.

Enemies use NavMesh for its movements.
