Shows how to access the plasma rifle and Supercharge/Soul Sphere, and where to find a few hidden but non-Secret areas, in PC Doom II level 10, Refueling Base. (See youtu.be/qoCcOGoPvVE for a video covering the actual score-affecting Secrets, and access classicdoom.com/maps/d2maps/10.htm to view a map of this level.)
The first hidden non-Secret area in this video is at the level's entry point, and is a chamber containing a shotgun and some health bonuses.
Nearby to the east is a large square block that can be activated like a switch, causing it to sink into the floor. This reveals a chaingun and, when playing at higher Skill levels, 2 or 4 Spectre Demons.
Next is a large, dark room on the east side of the level. Stepping across a small lit-up square on the floor will cause a pair of chambers to open in the north end of the room, revealing 4 Demons, some ammo, and a BFG 9000.
Last is a Soul Sphere and plasma rifle, located in the middle of the south edge of the map. To reach these objects the player must activate the nearby switch and also step on a floor trigger in a small space just across from the switch.
The switch and floor trigger control low platforms that will temporarily drop down to allow access. These can be activated in either order, so long as it's done quickly enough to let you get onto both platforms before they rise again.

![Beating unkillable enemies in TNT level 15, Dead Zone [Fast first half]](https://i.ytimg.com/vi/VewPRqKiDc8/mqdefault.jpg "Beating unkillable enemies in TNT level 15, Dead Zone [Fast first half]
*Note: This is nearly identical to an earlier upload, but here the video is fast-forwarded until the moment that the Lost Soul is released.* For the normal-speed video and more information see https://youtu.be/iKXnzorOxTI and the full description there.
Shows one possible way to beat the unkillable enemies on TNT/Evilution level 15, Dead Zone, by getting assistance from a Lost Soul.
Background: Due to an oversight in map design, some deaf enemies are forever waiting behind a tall barrier at the east edge of the map, where a player cant directly see or attack them. (There are 4 Sergeants trapped there when playing at Skill levels 1 and 2, a single Cacodemon at Skill 3, and a Cacodemon and a Pain Elemental there at Skills 4 and 5.)
Because of this, a maximum Kills score below 100% (especially at Skills 1-3) is a normal result after killing all reachable enemies.
Note however that Arch-Viles appear on this map at higher Skill levels and can resurrect killed monsters, allowing a player to kill them again and get a score of 100% or more, even if trapped enemies remain alive.
In this demo a Lost Soul is coaxed into a position from where it can make an attack charge over the barrier, striking any monster waiting behind it. This works because, in original retail Classic Doom games, living entities cannot cross paths at any height; So a Lost Soul attacking along a path directly above a target can still hit that target, regardless of any height difference.
Any waiting monster struck by a Lost Soul will typically retaliate. If its a flying monster (like those behind the barrier at Skills 3-5), it will usually move above the barrier, and then out into other parts of the level.
See https://youtu.be/YOU3UakpD8g for an example of a faster attack path for the Lost Soul.
If you have a rocket launcher, it can be used to great effect by firing at the Lost Soul as it crosses over the barrier. In the original retail Classic Doom games rocket explosions are infinitely tall, meaning that any living target above or below the rockets impact point can still take full damage. This is especially useful for eliminating the Sergeants trapped behind the barrier when playing at Skills 1 or 2.
(The video https://youtu.be/ml0ionIHLX8 shows how to find a rocket launcher on this map.)
A rocket launcher can also be used against any high-flying Cacodemons or Pain Elementals that cross over the barrier. Such enemies can sometimes be pushed across the barrier with gunfire, then hit with rockets as they get close to any enemies trapped below.
Notes on the making of this demo: This was made at the default Skill level 3 (Hurt Me Plenty). At lower Skills the trapped enemies are Sergeants, and so cant easily be seen in a demo (although they can still be killed), and at higher Skill levels there are more enemies in the open areas to be cleared away before freeing the Lost Soul. But in principle the tactics shown here can be used when playing at any Skill, as at least 3 Lost Souls are always present on this map when the player first appears.
