Shadowgrounds/The Water Treatment Facility

Keycard
From the start, head straight into the building. Take a right turn to the keycard and collect it.

To reach the second building, there are two routes. The southern route is slightly longer, but puts you in direct path of a pulse rifle. The northern route is faster (and allows you to use your pistol to break windows and walk through them), but requires a detour if you want to collect the pulse rifle before heading down.

Enter the second building (initially marked with a yellow-lit door). Enter the control room, and activate the terminal to remove the hazardous steam from the following room. Head to the east, and go into the elevator.

Lower Floor
After going down the elevator, you are dropped in a dark room with a large enemy; a second will come out of the floor fairly quickly.

Head to the western exit, and turn left to reach the keycard. There are two routes; the detour further south allows you to collect a spare pump to collect a shotgun. The alternate path skips repairing the pump. Head past the water pools to proceed.

Enter the control room to fix the ventilation, and head to the west to meet with security guard and scientist. Head to the right, and take a left to the north; enemies will begin to attack in force as you take the route. When you reach the next command room, you will need to hold out for a few minutes while the next door opens; enemies attack from the floor, and through the initial path you came through.

Once the door opens, go through it.

Water pipe
The final section is a long pipeline, with scattered enemies. At the end of the facility will be a large opponent. If you haven't done so already, upgrade your pulse rifle to inflict additional damage.

The enemy will spit projectile attacks while it is surfaced; if you are hit by one, you will be slowed down. In addition, it will also swing at you if you are too close.

Once the enemy is killed, the mission will end.

Weapons

 * If you missed the pistol in the introduction, a different one is in the room opposite of the first keycard.
 * The pulse rifle is prevalent in this mission. On the upper area, you can find them in the northern room of the first building, the first corridor in the second building, and the south-east storage room. On the lower area, you can find one in the same room you're dropped in, as well as between the water pools.
 * The shotgun is located in a bloody pool of water on the lower floor. To collect it, get a pump from the south-east corner of the area, and bring it to the pump in question.

Demo version differences
The demo version contains additional weapons near the pools. You will also receive free upgrade points to balance the short gameplay.

The next mission in the demo is ../New Atlantis: Centrum/.
