but be ready for a schooling !

Not really related but are there any decent guides on how to actually play TDM?

I think disrepute & vor did some per map guides.

Ok, I even did some searching for you:

I think you can find the rest from there.

What happened to dothedk.com? Those map guides didn't cover 1/10 of the stuff Level Up did, but that was their strength, you could skim through one and know the basics (important positions and angles, where does map divide, which player does what in normal play, which player does what in quad defense/attack).

Level Up guys did 3 hour long videos with so many details that it's unusable for someone genuinely new to TDM, they're more for someone who has hundreds of pickups under his belt and wants to improve the little things to step up his game.

dk's bible was better to show someone as his starting point. So where is it?

Guides won't teach how important the hierarchy of the players is.

Sure, I'm not asking how to be good at it, I just don't want to play like a retard and ruin the game for the rest of my team; I can learn to be good as I play.

You are absolutely right, tdm is a lot of fun, getting a bit thriller by this thread
