MAP26: Hydrotech is the twenty-sixth map of 1000 Line Community Project. It was designed by Philip Brown (Liberation) and uses the music track "Blackness Ahead (One Last Remembrance Trip)" by José Navarrete (CoTeCiO), taken from Doom 64 for Doom II.

Collect the super shotgun on your left and use it to kill the nearby chaingunner and imps then head straight forward to find a rocket launcher. Push past the zombiemen on your left and go through the door behind them to find more zombiemen and imps as well as a baron of Hell, then head north to an outdoor area with an armor that is guarded by imps to the left and demons to the right. Flip the switch next to the demons to lower a lift and ride it up, then follow the passage east and south past Hell knights and demons to reach the blue keycard. (This key is not actually used in the level, but you must step on it to open a route back to the starting area.)

Leave the blue key alcove and step through the now-open wall on your left to return to the starting area; you will see that the west windows have lowered allowing you to go outside, where two revenants (and a pain elemental on Hurt Me Plenty (HMP) skill level or lower) have teleported in. Pick up the plasma gun between the two doors in this area, open the west door to confront two knights and a cacodemon then look down the north steps to see a dark tunnel containing zombiemen and another pain elemental. Follow the tunnel west past two spectres to a T-junction and turn left, then follow the tunnel all the way to the end and climb the steps to find one or two barons of Hell and zombies guarding a switch. Flip the switch then go back to the T-junction where a door has opened to reveal an arch-vile; after killing it, flip the switch it was guarding to lower a lift that leads up to a room holding the red keycard, which is guarded by a mancubus and some zombiemen.

Step into the stream behind the red key and follow it back to where you found the plasma gun; the south door will open and release two revenants and two knights who are guarding some large ammo pickups. When you approach the pickups the floor will lower, sending you into a hall with a crowd of enemies including zombies, four knights and a pain elemental. Approach the door in the west wall, which will open automatically to reveal a smaller room with imps, mancubi and one or two more pain elementals, then press the button on the south wall to open a set of bars back in the main hall. Go back there and pass through the now-open doorway in the east wall, head round the corner to find revenants guarding a supercharge then continue following the passage until you reach the raised ledge on the south side of the hall. Press the button in the south-west corner to reveal a revenant (or arch-vile on HMP or higher), as well as opening the large door to your left and revealing knights, zombiemen, a pain elemental and a cyberdemon, which teleports to the water pool. Open the exit door at the back of this chamber and flip the switch behind it to finish the level.
