Played alllllllllll day and all night last night. Got 2 wins (Wraith, Mirage) overall and a bunch of top 5's and top 3's.
Played 2 rounds with a friend who is a 21 year old girl who literally never plays games. She was Lifeline, and would just do drops for us, and try to stay in the circle. Did 0 damage in both games. 3rd players were randoms.
Game 1: Top 3
Game 2: Champions!
My main tip is batteries. Have them, use them constantly. Your inventory should be mostly batteries, and you should almost never ever be below 2 bars of shield, ever. If you're in a fight and have empty shields, pop an escape skill if you have one, and go use them. If they are dumb enough to chase, they won't be able to heal the damage you were hopefully doing to them, or your squad can keep pressuring them.
