Just to keep it up in the comments for all the beautiful new people that play this game:
1) To find the jammers you have to use level one x-ray and search them in various places.
- The first is in the bushes in the parking lot.
- The second one is in the pool.
- The third one is under one desk in the classroom.
2) After you complete the D.va quest if you wait 2 weeks and do the homework for money in the weekend you will unlock the ability to use x-rays on sombra, both level 1 and 2.
3) for the D.va update, to distract Symmetra in the library first use your phone 1 time and after that talk to her and click "try to distract her" and that's it.
4) many users had trouble finding the shooting range in the Widowmaker update, it is where the swimming pool is, next to the P.E., when you click on it a pop up asking you if you want to go to the pool or the shooting range will appear.
If you have trouble with something you can ask, I play since the demo and I know everything on the game. I'm always happy to help remove some work off the shoulders of the Young and Naughty staff. All you guys are great and this game and his developer are the best.
