Half Life 2: Aftermath Map Pack

Requires Half Life 2, Half Life 2: Episode One, and Half Life 2: Episode Two to work.

All seventeen maps from the Half Life 2: Aftermath mod for Half Life 2: Episode Two.

From the ModDB page: http://www.moddb.com/mods/hl2aftermath

"Release 1 of the mod contains:
-11 levels created by Valve between 2012 and 2013, intended for Half-Life 3. Keep in mind that these levels were gameplay experiments, not actual storyline based levels.
-4 demonstration levels created by Lever Softworks to show various functions and NPCs not seen in those levels.
-weapon_proto1, a Combine laser-gun that shoot through walls, intended for Episode 3.
-hl2eb_weapon_proto1_debug, a command which toggles the Developer Console spam created by weapon_proto1.
-npc_combine_armored, an Armored Combine Soldier, intended for Episode 3.
-npc_wpnscanner, a City Scanner with a laser gun, intended for Episode 3."

The following maps are included (not in order on the screenshots):

A large portion of these maps have broken parts due to the issues with porting from a newer base of source into an older one, and my knowledge of scripting and mapping is not sufficient to fix them. These will not crash your game, but will lack full functionality. Nevertheless, I have chosen to upload them anyway should I learn how to fix them in future, or if someone else wants to take a crack at it, the files are here for them to use.

Two discussion threads - one listing bugs, the other a bug reporting thread - will be down below.

(Anyone who contributes to the addon in some way, like fixing a bug or adding scripting, and then provides me the fixed files, will be added to the credits list)
