The main components are the HL2 module Mission Improbable and Down Fall

--Notice: (1) If the M1 Sky Box is not visible (gray), please add+mat_force-vertexfog 0 in the startup option

(2) The server that has installed the "Prevent Three party Map Script Pollution Extension" can add this map to the whitelist. This map uses some global functions, but it will not cause pollution.

(3) The map is divided into two parts, the first part is the main body, and the second part is the materials and sound. Both parts need to be installed locally, while the dedicated server only needs to install the first part. The conflict between the two parts is a normal phenomenon. If there are purple black squares, please check if both parts have been successfully installed.

(4) In the desperate survival mode, the map will have some special content. The first two buttons can switch the number of advancement yards, which are 1000 yards and 3000 yards respectively. One switch is permanently effective, and the difficulty can be re selected after restarting the turn.

--map code

--Supported modes Currently only supports campaign and unbalanced confrontation modes

--Problem feedback Please provide feedback on the issue in the discussion forum and make unified adjustments when the time comes (this version also has some problems and I don't want to make any changes now)
