This page features a walkthrough for a memory in Get Even, related to the journey to Howard's storehouse. It's a part of the memory titled "The Offer", the last "big" memory exclusive to Black. The large part of this scene will be spent on traversing marshlands. As the area is patrolled by mercenaries, you will be given a choice - either to fight them or avoid any confrontation.
Get on your way. The first part of your journey is very linear, and the path will lead you to a small tunnel. From that moment on you may encounter enemies. If you do not wish to kill them, take care to move slowly (crouching when possible) and avoid staying in open spaces for too long, as you're easy to spot there. If you plan on engaging the enemies, pick them off one by one by sneaking up behind them or taking them down with a silenced weapon.
Regardless of your preferred approach, use the map and thermal vision to easily locate the enemies and establish their position and heading. Other than that, keep an eye out for anomalies. Scanning them will enable you to spawn little walls or other objects that can be used as cover.
Warning - Shortly after going through the previously mentioned first small tunnel you can find a track in the form of a newspaper. This item, marked in the picture, lies on one of the pallets between the container and the tall wall.
During your walk through the swamp keep an eye on your phone, as it will inform you of one of the areas that can be scanned (as a trace). Specifically, it's about the bottles standing on the rusty barrel, shown on the picture above. You'll find them near the main path leading through the swamp (it can be hard to track, as it's not particularly well marked). A bit further you'll see a picture, allowing you to move to the evidence room, but you're free to ignore it.
After a few moments, you will reach the second major section of the swamp. Also here you'll encounter numerous hostile mercenaries, and it's best to try to circle around them either from the left or the right side. Your objective is to reach a small tunnel, near an opened gate in a fence.
You've got one more area to cover, also full of mercenaries. One thing that will help you is the abundance of high walls, making it easy to hide from or avoid some of the enemies.
The stone path will lead you near a large building. Find a door with the letter C. An attempt to enter the storehouse will end in you finding yourself in the "void". Here, you'll have to pass through subsequently unlocked area and listen to Howard's conversations with Black. After some time, you'll have unlocked the Beyond the Evil trophy, and the memory will be completed.
