Additional information

This time I tried to aim for a 3D shooter. I was not really sure if I should have done it in third person or first one but I opted for developing The Lost in third person. I had two main reasons, the first one is because of the assets I have used and the second one is that I though that a third person shooter will be easier to implement than a first person but maybe I was wrong about that last part.

The theme of the game is that you are trapped in a an arena and you have to kill the incoming enemies and complete all rounds before the time runs out. For each round completed, you will have a little break of 30 seconds that you can use for example to reload your gun. You can choose to either shoot the bell or wait till the timer reaches 0 and the next wave will automatically start.

Out of curiosity, for those that like interesting facts, this project was named after the television series and the character in The Binding of Isaac: Rebirth. Both are worth to keep an eye on.
