Option 1 - Easy Way

Put gg_lala_crash_v2_2.bsp into your maps folder, if sounds dont work then use option 2

Option 2 - Normal Way

Put this into cstrike folder, the reason it does not go into maps instead is because I have added sounds so you have to put it in cstrike or if you want you can check what's in it :D
If your running a server then you do the same or for some reason its incorrect put it in manually 
If there are any bugs/ideas post them below :)
