Tralala1

Tralala crazy advantures.
My first L4D2 campaign ever inspired by hehe and shenmejb awesome series.
Anyway, map 3 is a little bit hard so bellow are few hints for those who are frustrated but still want to finish it:
* you can (mostly) stuck rotating barrels for other players when you stay on it
* there are ~5 hidden buttons in the 3rd map which opens teleport for players behind
If you are still lost and did not give it up, check this derp's video: https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=2899301290 (but it does not contain latest campaign version nor 3rd map buttons/teleports).
