Marathon Season 2: How to Ruin Someone's Day With the Sentinel Shell
There is a fine line between playing defensively and just being a paranoid camper, and Marathon's new Sentinel Shell absolutely obliterates it.
Extraction shooters heavily favor the hyper-aggressive crowd. Usually, the person who pushes a room first with a shotgun walks out with all the loot. Bungie just expanded the Marathon roster to eight playable Shells with Season 2, and the new Sentinel is here to specifically punish those aggressive pushers. It is officially labeled as a Defensive Strategist, which is just a polite way of saying you get to fill a room with traps and watch the other guy panic.
If you are tired of getting flush-bombed out of your cover or getting sneaked up on while trying to rifle through a storage container, this kit is going to be your new best friend. I have put a good chunk of hours into testing these abilities, and I am going to show you how to actually use them to stay alive.
The Sentinel Toolkit Explained
The entire point of the Sentinel is to force hostile Runners to fight on your terms. You are basically turning the local geometry into a meat grinder.
How to Actually Survive as a Sentinel
Before you waste three matches trying to sprint right into a heavily guarded compound like an assault tank, you need to understand your role.
You do not kick the door down. You are the person who makes sure nothing comes through the door behind you. The Sentinel really shines when you are playing solo, especially in the new PvE mode. The standard loop is simple: you find a room full of unlooted containers, you slap a Snare Mine on the only entrance, and you loot in peace. If a UESC patrol or a hostile squad tries to sneak in, they hit the mine, take damage, and get immobilized. This gives you plenty of time to stop what you are doing and introduce them to your shotgun.
If things get chaotic and a full squad pushes your position, you drop the Defender System immediately. It eats grenades and rockets so you do not have to, and the passive buff to your weapon stability makes holding your ground significantly easier.
Managing Your Counters
No class is invincible, and the Sentinel has a very obvious Achilles heel. Signal Jammers will completely fry your Prey Tracker, leaving you totally blind to approaching threats.
If someone drops a jammer on you, your tech is useless and you have to rely entirely on raw gunplay and your passive Castle Doctrine buffs. Since Castle Doctrine only speeds up your close-range weapons like SMGs and pistols when enemies crowd you, you need to ensure your base stats can handle a sudden close-quarters brawl. If you are struggling to stay alive when your tech gets jammed, you should probably check out my Marathon Cradle system guide to permanently beef up your base damage and health pools.
