Your seat is so hot Trophy in Trackmania Turbo
Your seat is so hot
Complete a track in hotseat mode
How to unlock Your seat is so hot
From the main menu go: Multiplayer => Hotseat. Player one will set a time on a track, then player two will have a limited time (until their petrol runs out) to beat the time. As both people play at different times, you only need one controller. Finish the round then the trophy should unlock.
