Well, we had a crazy time on RHL with our very first game of Das Boot. Methinks we'll want to refine some of the rules a bit but it was a real trip! Rex has begun to process the mountain of data from that session, but in the mean time, I transcribed a few pieces of the Halo preview in the very last PCXL issue, along with some related material from other previews. Here's a snippet:
NPC humans who you'll meet along the way won't be under your control but you will be able to join up and help them in their battles. You can bet those vehicles that have a driver and a gunner aren't just for the multiplayer experience. Nope, you'll do whatever is necessary as battle and missions progress and expect the AI to be alongside you.
You might find this an interesting read. Go take a look.
