My favourite kinds of Halo come in two flavours - one is hardcore 4 v 4 slayer and objective. The other is insanely massive 8 v 8 Valhalla style shenanigans. This map is built to honour the latter.
So, Odyssey is a classic 2 base BTB map. The map itself pays homage to several BTB classics but first off it's important to note you can no longer camp on the mountain, nor peek over the top to the enemies base and pepper them with bullets as they spawn.
Vahalla - One of the most important things for me when designing all of the spaces was player movement. You can get around on this map really quickly, even on foot, thanks to helpfully placed Mancannons.
Sandtrap - I used to love that Banshee rush at the beginning of matches on Sandtrap, so I've replicated that Power Weapon rush - I've drawn it out a little though, and if you don't get there first, you'll be happy to know theres a way to quickly get back into the fight, without being stuck in the middle of nowhere thanks to...
Blood Gulch/Coagulation - ...teleporters! One at each base, leading to the middle, as well as one at the Middle structure, which leads to the other side of the map, and the Rocket Platform, which in in itself is a little nod to Ascension.
Standoff - Vehicles play a very important part on this map, especially the warthog. The only difference is, there's a lot more vehicle-wise to play with. 2 Hogs per team, as well as a Ghost, and 4 Mongeese. I know it sounds a lot, but on the limited playtesting I have done, it seems fine.
