The first part of this episode is rather easy, so continue until you are inside the building. Grab the herbs here and continue. The first room has FOUR enemies in it and they can clog up the hallway, so it is best to take them out as they come through the choke-point.
Get through the character change / stealth area and then slowly work your way around to the box. Use Natalia here and kill whatever comes at you, then continue on. You’ll get the Control Room Key. Kill the enemy with the brick and let Barry.
Continue on past the control room and through the hallway. May as well kill the enemies in the hallway here. Use a brick to stun them and take out the growths on the floor. Head to the power switch now and turn it off. Go through the nearby door and make your way to the entrance.
Head up to the Control Room watching out for the two enemies o the way. Here you may just want to activate the doors and run to the flame-breathing thing with just Natalia. Barry should survive, but be fast. Plus he will book it to you once you have it turned. Turn it again and we’re outside!
Keep going until the first Revenant encounter. Fairly easy, just find the weak spot with Natalia and take it out. Continue on to the woods area. Here you should really just run through it with Natlaia. After all, at the end past the small building you can hit the door and all enemies will be gone. Continue on and be sure to grab the Firebomb before getting to the logging area.
This area, just like Claire’s, is REALLY difficult. Before we do anything, we MUST prepare our way to the second switch. Open up the doors and kill the Revenant patrolling the hallway. Open up the next couple doors (ignore the one where the Revenant is - no reason to fight him at all) and then open up the door at the end of the building. With this done head to the locked gate and have the sequence start. Toss a Firebomb Bottle at the two Revenants that break down the wooden wall.
Take control of Natalia through this segment and let Barry handle the Revenants (we are essentially sacrificing him! Heh). When you get to the first switch, if you see many Revenants outside the room kill most of them using your second Firebomb Bottle, just like Countdown Mode. Now we just have to run to the other switch using the way we prepared and that is that!
We are in the clear afterwards, so congrats on beating Episode 1’s Invisible Mode with Barry.
