General objectives of the stage: Dead End is the first of four stages of Dexter Industries mission. This stage consists of two main parts and at the beginning you have to disable security systems - both, primary and backup.
You start the mission at the entrance to the Dexter Industries complex and this is the only place where you do not have to sneak. If you want, you can make your further gameplay easier by obtaining factory guard disguise. The easiest way to do it is to trigger the alarm in one of cars parked near. Notice - on lower difficulty levels guards may ignore the alarm and in this case you can obtain the disguise later on.
Regardless of whether you decided to obtain a new disguise right away or stay in default Hitman's suit, your first step should be getting inside the first post shown on the above screen. Regardless of the difficulty level, there should be two persons in the area. Wait until they turn around/walk away and go through the shutter. After you get inside, interact with primary security system console.
Now you have to decide how you want to approach sawmill visible in a distance - a second post with backup security system can found be near there. On lower difficulty levels it is best to go through the second shutter (screen above), because the main road to sawmill shouldn't be guarded by anyone.
On higher difficulty levels the mentioned road is guarded by at least one person. So it is best to return to the starting place and then head left. Locate a shutter shown on the above screen, but before you go further, make sure that no one looks at this side.
If you decide to walk near the main road, you have to watch out enemies located on the left side. Use subsequent parked cars and other objects as covers.
If you move through the area left from the main road, you should stop at the cabin shown on the above screen. You can perform two actions here: easily obtain factory guard disguise (wait until one of guards enters the cabin) and take a keycard lying on the table inside the cabin.
A keycard found in the cabin unlocks the access to a storage room located on the other side of the road, between first and second post (screen above). Inside the storage room you can find proximity mines, AH 74U submachinegun and factory guard disguise (you might take it if you haven't attacked anyone yet).
Your current target is a second post shown on the above screen, located to the right from sawmill. Watch out guards staying in the area, using covers and Instinct. There are plenty of containers in the area, where you can hide bodies, so you can decide to eliminate single enemies.
After approaching the second post, place yourself at its shutter but do not go inside until local guards end the conversation and walk away. Only then carefully go inside the building and interact with backup security system console.
