There was a really neat fog of war with the covered tunnel areas, and we were forced to explore most of it because we had to find the energy crystal left y a previously wiped out recon team to power the commo unit to call the retrieval boat.
He used a modified set of rules called Swatters by Ganesha Games. It was a great set and the game played really well. I think if I ever do a bug hunt game again, I will use these. You maneuver fire teams and it really gives a good feel of pouring on massive firepower in a desperate attempt to stop the bugs.
Here are a few pictures, enjoy!
