Just figured I would leave this here for anyone who might be interested in it.
It's been a while since the "Be The Spy" and "Be The Medic" guides were created, but I finally got around to making the "Be The Pyro" TF2 Pyro Guide. It's great for new players and returning players that just want to brush up on weapons, skills, and tactics.
The Pyro Guide is informative, slightly humorous, and even is timestamped for easy navigation to certain topics, such as dealing with the Spy. So, go ahead and check it out, learn to burn, and leave any comments or questions either here or on the video link below!
