My friend Corey Croot (has to be the most fun person to play 40K against) had a unit of Firewarriors with EMP grenades and the same model blew him to bits 2 games in a row. The first time was just funny but the 2nd time was so priceless he now has the model displayed in a tiny case as he took out over 300pts by himself LOL.
Also my ex-wife played us in Carnage once and rolled nothing but 5s and 6s the whole game. Needless to say my friends were stunned.
