each time I get to test chamber 02 it crashes. not exactly sure if I'm just being an idiot
video of me opening the portal.bat file and playing test chamber 01 to show the game crashing.
i have never seen this problem, but i recommend talking to the people in the discord instead since the forums are not as offen checked!
Try checking in Source_Upack > portal > maps and make sure testchmb_a_02.bsp is there and if that doesn't work check Source_Unpack > portal > maplist.txt and make sure that testchmb_a_02 is in the correct place (underneath 00 and 01) and if none of those work ask in the discord or just reinstall the game
