I AM CURRENTLY WORKING ON A REWRITE FOR THIS ENTIRE CODE TO MAKE IT MORE EFFICIENT AND SCRIMMABLE. < When I have the time.

Update 3/10/22: Wow, finally. Looks like this code will soon be useless. Thanks for playing it!

Update 6/7/23: Hi. I made a new one that rebalances the game I'd want it to be like.

I was really, really bored one day, and decided "I'll make Overwatch 2." Here is that idea, imagined.

Not really much to it, I'd have to say.

Uses an extremely small snippet from SVB's Overwatch 2 patch, just the reduced ultimate charge from tanks script.
Thanks to MushaSnazz for inspiring the idea for Lucio's new boop mechanic, it's really cool! YWZ53
