Yes, only ROS. Soo it means Rules Of Survival .(the best PUBG game on mobile from my experience) It takes a huge chunk of memory on your phone, tabs, etc. but it eats less data if you want to play while you are outside (like me) 
and if you want to play with me, add me. I would love to play with others.
Btw pic this is outdated, too lazy to picture it again ;-; (im Gold IV)
So yeah come play with me especially when you are a newbie. I would help (sometimes)
