I was a bit sceptic when I saw the video. How the heck someone who got the game 5 months ago be so skilled while us 1-2-3-4-5-6 years LFSers can't. Glad I solved a mystery on LFS Forum.
After you drifted, hit F1 instead of F2 so you can automatically watch the replay. You can edit the layout when the replay is running. Just look where your car goes and put objects following the cars path. Then record and put it Youtube so everyone says 'Awesome drifting!!!111111!1!'.
UT as always about killing everyone with no reason and capturing flags anyway. I wanted to download the thing on Steam and see if it was worth bu it seems like it's not.
