I just recieved the PDFs for a game called Hour of Glory. I havn't read through the game yet, but it looks outstanding.
The theme is a WWII assault on an Austrian stronghold by an elite British agent. One player obviously takes the part of the agent and the other player the guards at the stronghold.
If that theme tickles your fancy then follow the link above and check out the photos and game info at Board Game Geek.
I'm almost drooling over this game.
