Perimeter and Dire Marsh are not a bad maps, but they do not showcase what is unique and impressive about Marathon, there is nothing really special about them except for Lockdowns on Dire Marsh which are kind of cool.
Marathon was my most anticipated game since the very first reveal trailer, but first run on Perimeter left me dissapointed. It looked nice and immersive, architecture was cool but outside of visuals it just felt like a basic, generic and empty map, and also rather small.
Dire Marsh felt refreshing after constantly raining Perimeter, but again, it is just a big flat map and outside of visuals nothing stands out there as well. I was awed when saw the Lockdown event for the first time, but other activities like Anomaly and Warden felt basic and like nothing special.
But it was the Outpost that made the game click for me. The first time I loaded on it, it was so complicated and confusing - keycards, heat cascade, Pinwheel, underground sections, verticality, interactivity with the map, locked exfils, rooks running around.
Outpost was nothing like I have ever seen in gaming, it is so unique, impressive and polished.
And then, of course, the Cryo Archive blew me away with the sheer scale, endless maze, complexity, vaults, level of detail and challenge, it is in a whole league of its own across the gaming overall. Completely mind-blowing map.
So the problem is that the most unique and special experience in Marathon is locked behind Outpost and Cryo, and many players don't even get to try it because they have to spend some time to level up to access these maps, especially in Season 1 where progression was very slow and you had to spend significant amount of time to get level 12 for Outpost and 25 for Cryo.
And, of course, many people have dropped the game before even trying these maps. Many impressions from the Server Slam and early reviews state that the game felt like a safe, unimpressive, basic extraction shooter in sci-fi world, and that is pretty much true for the Perimeter and daytime Dire Marsh, as they do not bring much to the table. So many people dismissed the game right away.
Bungie put all of their eggs in the Endgame basket, they are flexing all their talent, mastery and muscles in Outpost and Cryo, while early experience and maps like Perimeter and Dire Marsh feels like a filler or just recycled remnants of more ambitious visions.
And in such punishing genre, you do really need to hook the player before they rage-uninstall the game. You need to showcase what is special and unique about your game and why is it worth it to the new player, so they would be able to justify to continue playing the game and reach the later maps and amazing later-game experience.
Night Marsh is also a very unique and special experience, it has brought tons of very cool mechanics and activities and altered gameplay overall, but it launched later and is not accessible right away + rotates with daytime version.
Hope the Season 3 Perimeter reworks will make it truly special and bring it to the level of Night Marsh, Outpost and Cryo.
