This is the part that kills the game immediately for me. I like the artstyle and everything, the gunplay looks to be somewhat slower Destiny 2 gunplay, which I also conceptually like. But I already play Destiny 2, I'm not going to pay money again, to just play Destiny 2's PVP, but slower with an extraction shooter twist.
You know what I like about D2's PVP? No fucking commitment. I put on some guns, I hit queue, I get in, I shoot some dudes for 10 minutes of uninterrupted action, get chain killed by 4 supers in a row, then the match ends and I immediately queue for the next one, and I get guns and armor for doing it.
As a singleplayer or co-op thing, extraction shooters are a neat twist on roguelites and permadeath, especially if they let you go back into the map and find your previous corpse to try to save your gear, and all of the decisions that come with that.
As multiplayer games, extraction shooters are just BR games with more empty downtime, since 90% of the match is running to a place, but you also have to spend 20 minutes waiting for your friend to get out, then re-gear, then check quests, then find the map to play, then ready, then matchmake, then load. Then you get a match where you either get in a fight in spawn and you have to evac because even if you won, you're fucked up, or you get one of those matches where everyone else had spawn fights and then left so you just run to your objectives. The risk factor also pushes the most roachlike styles of gameplay known to man, of camping a single room for 45 minutes while watching netfilx on the other monitor.
I generally liked what I saw of Marathon, but Jesus Christ himself couldn't get me to drop money on a PVP-only extraction shooter, when I can probably pay $10 more for the yearly Destiny 2 expansion and get basically the same gameplay with three times the content, and the ability to not get roached on by shitbucketing teenagers who play the game for 19 hours a day.
Either they should've had a PVE/Co-op mode in the game, because the AI enemies in Marathon actually seem way more interesting to fight than most other Tarkovoids, or if they wanted to stick with PVP-only, they should've made it free, but they chose the worst of both worlds.
