[b]Map filename[/b]
?unattainable_1 (First stage complete version)
?unattainable_1_low （First stage optimized version. This is for running servers or eight-player lobbies mod, or when " ED_Alloc no free edicts " pops up when entering the complete version. What's the difference? This version removes hundreds of wire entities to reduce the number of entities to prevent pop-up errors, so if you are playing by yourself or play with other 3 player, it is recommended to play the complete version.）
?unattainable_2 （Second stage）

This map is not guaranteed to run properly with a large number of mods and a large number of players, so please disable the mods yourself if the game is crashing

[b]Game Tip[/b]
? Please enable the game hints when you playing, otherwise the map will not play properly. (Options - Multiplayer - Game Instructor)
? If you are unable to pick up objects, please check if there are other mods or maps that affect the functionality of this map. Inability to pick up objects will prevent you from playing properly.
• The Tank and Witch in the first stage are spawned by the game director, not pre-placed by the author.
• If you are playing solo with bots, guide your bots teammates to pick up guns and buy weapons for them, and try to keep them alive to assist you.
• The difficulty of the second stage depends on how many human players and the difficulty of the game, if the bots mod will affect the operation of the map please disable it.
• If the difficulty is too high or too low, choose a difficulty to play on that suits you.
• When the tank is coming, stay away from the car, do not forget that you are playing the L4D2, the car can be whacked fly by the tank .
• Vending machine to buy something does not drop, wait a few seconds should be restored. 

I'm glad you play my map, if you play happy I will be more happy.
This is my first L4D2 map, My ability and energy is limited, please bear with me for any shortcomings ~
