MAP09: Stronghold (TNT: Evilution)

MAP09: Stronghold is the ninth map of TNT: Evilution. It was designed by Jimmy Sieben, with minor additions and touchups by Ty Halderman, and uses a music track shared with MAP01: System Control. It is notable for having many enemies. This sheer number of monsters almost entirely consists of hitscan-employing troopers,  sergeants and  chaingunners, who will often take potshots at the player from balconies and through windows. Somewhat confined layout of the map also adds to its difficulty.

Secrets

 * 1) After getting the red key, you'll see a narrow hallway through a window to the right. Press the use key against the window to lower it, letting you access the hallway. There is a blur sphere at the opposite end.
 * 2) In the same room as the first red switch (at the west end of the map) is a wall with flashing blue lights. Lower the wall with the lights like a lift to be taken up to a secret cache.
 * 3) At the south end of the map is a long hallway with a series of silver doors you must open before getting a backpack on a pedestal at the end. When you pick up the backpack, several alcoves open in the hall behind you, releasing enemies. One of these alcoves has a triangle on its back wall; open it to access a secret area.
 * 4) At one end of secret #3 is a second triangle on the wall; it acts as a lift up to a secret-in-a-secret, at the end of which you'll find a berserk pack.
 * 5) At the north-northeast corner of the map is a room with a square sunken nukage pool. On the ledge in the southeast corner of the pool are two red lights visible in the walls. Open the wall between the lights to access a secret room
 * 6) See secret #5 (the door and room sectors are both tagged as secret).
 * 7) At the eastern end of the aforementioned nukage pool room is a silver alcove; step in to be taken down to a new area. In this green room, open the wall to the right (with yellow lights along the bottom) to activate another lift up to a secret area with two teleporters in it.
 * 8) Inside secret #7 is a sunken brown floor alongside an "L"-shaped computer terminal. Stepping onto it registers a secret.
 * 9) While still in secret #7, take the right-hand teleporter. It takes you to the raised area back in the green room.
 * 10) Return to secret #7 once more, and take the left-hand teleporter. It takes you to a secret corridor all the way back near the level's start.
 * 11) In the stairway leading up to the room containing the exit door, there is a wall with two blue triangles on it. Open it up to reach the last secret.
