It's really easy. Bomb as much as you can for those fifteen matches. I'm being dead serious - I went into control once, went 0 - 7 and got tunnels Thunderlord. Hour later got hard light.. and then there is what happened last night. I was doing Vanguard roc and it put me in a match with randoms who literally were at the very end of the strike. I literally only took two steps and it was done - and I got mida multitool 2.0
