PlayerUnknown's Battlegrounds. PlayerUnknown's Battlegrounds has been a runaway hit over the past several months, selling a staggering 20 million copies worldwide -- in spite of being an unfinished, buggy game that makes beefy gaming PCs weep. But according to a Chinese press release from publisher Tencent, you'll soon be able to play the hit game on your phone.  The catch: It's coming to China first.  Known as PUBG for short, the game has you and 99 other players parachute onto an island filled with deadly weaponry and fight to the death. If you're the last person standing, you win. It's a game where winning is about strategy as much as aiming a weapon, and where even cowering in a bathroom can be a nail-biting experience.  Tencent gave no details on release dates in China or plans to expand to other markets, but it's probably safe to assume a game with such a huge following will hit western markets sometime in the future. Rules of Survival has a similar feel to PUBG and you can touch a button to go prone, letting you lie in wait in the tall grass. Why wait? But if you're dying to play PUBG on your phone right now, we may have a solution. Today marks the release of a clone named Rules of Survival (iOS | Android) that shows a lot of promise. It shares a lot of the same characteristics of PUBG: a huge island map, vehicles to drive, and the same cutthroat playing style where there can only be one winner.  In my testing the controls were spot on, I had little to no lag and graphics were smooth as silk on my iPhone 7 Plus. It's a lot of fun to play even on the small screen and miniaturizes PUBG's core concepts well -- even if it didn't give me the same feeling of fear I felt playing the original. Just like PUBG, you'll need to manage your inventory and it's easy to do using drag-and-drop touchscreen controls. One small difference in Rules of Survival is that it increases the player count to 120 players total -- impressive, and different from most other PUBG clones we've played on mobile. (We've tried roughly a dozen, but none have impressed us as much as Rules of Survival so far -- and some ask for way too much personal information.)  You can fight alone or
