Master Chief and Commander: It's Halo 3 but with boats and a naval battle against a Scarab.
Who knows where the germ of an idea for some mods comes from but with, ahem, Pimps at Sea I can take a wild guess: "What if Halo 3 but with boats?" Well, what if?

Available now on the Steam workshop, Pimps at Sea lets you get nautical with the Halo 3 toolbox in a co-op mission set across some tropical islands infested with Covenant. The twist of course is that two big 'ol boats are sailing in big lazy loops in and around these islands, and any enterprising Spartan can hop on board.

I mean… it's not complex, but it is a lot of fun. You ride about while a very good Sergeant Johnson impersonator barks out orders, climb the mast and take pot-shots, fire cannons at things, and if you fancy hop off and engage the Covenant forces with a plethora of vehicles.
