This is a video that gives you just enough CS knowledge that you can have fun playing casually without thinking the game is impossible. I learned this from a bunch of different videos recently and I compiled it for my friends who don't have experience with CS2 and aren't having a great time with it.
What I went over:
How to aim/crosshair placement
How to learn a map/bombsite
What each utility is used for
How to use utility based on the situation
How to comm
How to learn call outs
Importance of call outs
Trading vs Baiting
