To make my Unity project a little more interesting I made it into more of a game by adding some basic elements.

Enemy Spawners

Instead of manually placing each enemy I made a spawner script that I can attach to empty Game Objects and place around the map, specifying the number of spawns and the time between spawns.

Health Packs

For the player to recover health I made a spinning health pack inspired by the ones in Team Fortress 2. When the player collides with a health pack they recover 1 HP.

Taking Damage & Game Over Screen

If an enemy manages to collide with the player they take damage! If you lose all your health it's Game Over!
