This guide is how to play Half-Life 2 in Bear Part: Adventure!
You can do this in almost all source games!

If you own Half-Life 2, go to the file location for that. (steam/steamapps/common/Half-Life 2/maps/)
Now copy all of the map files into the Bear Party: Adventure file location. (steam/steamapps/common/Bear Party: Adventure/maps/)

While in the game, open the dev console (enable it in options!) using the ` key.
Type: map d1_trainstation_01.
You will now load into the first map.

• The game will not play character voicelines!

• The civvies will be using a unique model!

• Some parts of the game may not work very well.

• The pistol will also be a unique weapon. (Don't let anyone shoot you!)
