I've had this idea on my mind for a while, to release the map sources of ts_untergrund19 as an example of a finished map.
But then, I asked myself: why not release more than that?

Maps

Examples

There are quite some examples in the provided maps, from brushwork samples to entity setups and sequences.
Most of these are adequate for beginner mappers, although some examples are slightly more complicated (e.g. the mortar launch panel in de_kobbl).

Entity setup	Map
Moving terrain setup	sandstorm_0
Osprey getting destroyed mid-flight, pulling the players out of itself	sandstorm_0
Human grunts getting down in an elevator and running forward via scripted sequences	acdm_roomwar
Breakable computer CRT monitors with gibs flying out of them	acdm_roomwar
Large explosion sequence	acdm_roomwar
Air jump fans similar to Xen jump pads	ts_untergrund
Breakable map design, also demonstrating a deforming floor piece	ts_untergrund
Breakable projector setup	ts_untergrund
Laser scanning sequence	sc_zvezde
Tractor beam elevator	sc_zvezde
(Rather amateur) car chase sequence	jungle_mission
Barrel that explodes only in a specific spot	jungle_mission
Teleportation sequence after healing	fun_kobbl and sc_kobbl
Manual mortar launch table using func_trains, func_doors, multi_managers etc.	fun_kobbl and sc_kobbl
Crate lid that falls off to reveal weapon pickups	sc_kobbl
A continuous cycle of several ambient_generics using a func_train and 4 path_corners	de_kobbl
Zombie breaking a wall	c1e2p1

Happy mapping! -Admer

To-do: maybe I should write tutorials for some of the complicated entity setups. Hmm...
