Shogun 2 and Team Fortress 2 crossover

Wow, I did not see this coming. If you pre order Shogun 2 on Steam and you own Team Fortress 2 you will receive this pack. You can also buy this stand alone on Steam. If you already pre ordered Shogun 2 off Steam don’t fret, you will still get the pack as long as you already own Team Fortress 2.

What other cross overs would you guys want to see Sega do?
