Encourage them to try different weapons to find something they like. Try to teach them how to take advantage of the aim assist. Help them filter through the inventory and understand what the weapon stats mean.

I sort of played an overwatch role, making sure to keep an eye on her screen and give tips where I can.

This is literally the only time she's played a game with me, save for Nintendo.

Gearbox fucked up BL3's split screen so badly that I'd call it unplayable, and she agrees, so we haven't played it yet.
