Move down the hall and snag the Power Node hanging on the right wall. You'll need this soon enough to unlock a door that contain the Vintage suit schematic and other goodies.
Equip your new gear and head to the next room. There will be more Necromorphs that can be dealt with your Ripper. Meet up with Ellie and you'll find that the door is jammed. Check around for a Detonator ammo schematic before heading to the processing plant.
You'll be moving through a large, zero gravity waste disposal area. First shoot the canister to open the main door. You'll be greeted by a few Lurkers who can be killed off with your cutter. Next move ahead to a field of spinning turbines. There is just enough room to squeeze passed these un harmed, but if you want to even more breathing room, stasis them to slow down their lethal force.
Next, there will be a few sliding walls that are moving too fast to get by. Stasis them and move by quickly to reach the next obstacle. Here, there will be rows of spinning blades that must also be stopped with stasis. finally you'll arrive at several rings of fire. Pass by each of them as the flames dissipate.
At the end of the tunnel will be a large Necromorph that shoots powerful projectiles. Kill it and grab the semiconductor it drops. After this battle, continue on to find the exit out of the plant. You'll meet up with your friends in the next area. Take the time to grab a Power Node and a schematic for large health packs before moving on.
