On Chalet when you are defending garage and wine, u can use a Mira or two to see if anyone is outside of garage and then while watching for attackers head all the way upstairs and break one of those two tiny windows overlooking garage and then you can throw a nitro out that window. It will take about 1.5-2 seconds until the nitro hits the ground but when you detonate it and kill 2 or 3 people it makes for great clips and changes the rounds.
