I use them sometimes. I use them like a predator missile. I shoot them straight up for a few seconds, or til 1/3 of the fuel is gone, by then you are WAY above the map and can see the whole thing. Then just come down slow til you find your target then boost
I use them a lot. I wish it was just 1, and for a 5 KS though. Then you'd see them like crazy, especially in Search.
My favorite thing to do is use them in FFA...get 29 kills, then wait til someone is just about to turn the corner and smash them in the face with it. Results in a hilarious game winning killcam. Also fun to use if spawn trapping...I've lost count how many
triple kills I've had with a single Valkyrie.
It's what I get a lot in CP's and seems to work well seeing as I play Domination a lot. Allows for a quick kill of flag cappers. I annoy my friends cuz when I launch it I hum "Ride of the Valkyries" until they explode.
