Cultist Base Sentinel Batteries
Sentinel Battery 1
The first battery you find on the Cultist Base level is a bit tricky to get. You’ll need to turn back to look at the door you came through where you should see a small ledge to the left. Jump dash to that and 🤡you’ll find a small cave with a green punch switch that will open a gate to the energy lift 🅘under the main area with the hanging bombs. Head back and use the lift to reach the battery.
Sentinel Battery 2
The second Cultist Base Sentinel Battery is an easy get. Just head up the massive drawbridg🐓e and check left to find it at the end of the corridor.
Sentinel battery 3
The third Cultist Base Sentinel Battery is in an area with two lifts that move up and down. To reach it use the energy lift to jump to the upper lift🥃 on the left. Go into the area that takes you into and then go to the lift on the other side and use that to go up another level. Follow the corridor around and you’ll be able to drop down into the area with the Battery.

Super Gore Nest Sentinel Batteries - map 1
Sentinel Battery 1
You won’t see the first Super Gore Nest Sentinel Batteౠry on the map when you start as it’s in an area you won’t reach until you’ve used the yel🌸low gore key and started looking for the red gore key. You’ll end up in some radioactive sewers and reach this area:
Instead of jumping up to reach the destructible grate go through the tunnel underneath to reach the first Sentine♉l Battery. 💖;
Super Gore Nest Sentinel Batteries - map 2
Sentinel Battery 2
The second Super Gore Nest Battery you’ll discover shortly after dealing with the Buff Totem area with all🧸 the lava. Again, it’s one you&rs🀅quo;ll pass as part of following the objective, after you punch out the block to climb the building it’ll be to the left of the objective.
Sentinel Battery 3
You won’t be able to get the third Super Gore Nest Battery until you have the blue gore key. When you do head ba𒊎ck to the giant meat tower you saw right back at the beginning of the level. The blue gore key wil🌌l get you inside where you can use the energy lift to reach a big climbable wall and access a corridor that leads to the third batter.
Arc Complex Sentinel Batteries

The first Arc Complex Sentinel Battery is near the Slayer Gate and easy to reach. Just jump on to 💖the climbable wall and then down to the ledge it overlooks. You should be able to see the battery easily from the wall.
Sentinel Battery 2
The second Arc Complex Sentinel Battery is another easy one to get just after you shoot the first giant tentacle. You’ll see it through a window shortly after you leave the the gun and can just enter the room to get i🐎t.
Sentinel Battery 3
The third Ar𝔉c Complex Sentinel Battery is another one you have to pass as part of the mai🧔n objective. When you get to the purple slime area use the swing bar to get over the fence and then dash to the box it’s on to claim it.

Mars Core Sentinel Battery - map 2
Sentinel Battery 1
You can’t get the second Mars Core Sentinel꧟ Battery unt🗹il after you’ve fired yourself from the cannon. After that it’s along the route you have to take although it might look a little out of the way initially.

Tara Nabad Sentinel Batteries
Sentinel Battery 1
You’ll see the first Taras Nabad Sentinel Battery through a grate in 📖a cliffside when you make the big jump at the opening of the level. To get it head over to the other side when you land where you’ll find a lower platform with a smashable wall that opens into a tunnel that leads to it.
Sentinel Battery 2
The second Sentinel Battery on Taras Nabad is one of the hardest to find in the game, requiring you find a switch that&♊rsquo;s hidden in a way that isn’t introduced until the next area. Bluntly, you have no idea what you’re looking for until you’ve moved on and left the area. To get the battery, which is in a sealed area, go to the end of the courtyard with the big statue, and look for this smaller cracked statue decorating the wall. Punch it to break it and reveal a switch that will open the gated area above the battery. There you can climb the wall and jump to punch the chain that will releaseꦰ the weight and smash through to the battery.
Sentinel Battery 3
The final Taras Nabad Sentinel Battery is, fortunately, easy to get. When you climb out into the area with the fallen titan just look behind you as you come out of the hole and🔥 you’ll see it in the corner waiting for you.
