I have played only mobile version and here is my review:
Graphics: The graphics adjust itself according to the specs of the phone. Mine is Redmi 4 which has 3 gb ram, Snapdragon 435 octa-core processor, 1.4GHz max , Adreno 505 GPU. It runs on low settings in this phone and even in that it has slightly lower frame rate. But it rarely causes any lag and still appropriate to play
Controls: I think they really tried their best to setup best possible controls to play. Its really hard to setup the best control for FPS in mobile. So to make it more easier they added features like sprinting, moving eye, gyroscope control and picking up best supplies automatically. In recent update they added shoot button in both left and right side. Earlier it was only in right side. Although you can change the control positions.
Also it has leaning feature which allows you to lean on left and right side so that you can shoot an enemy while hiding behind a wall
Although obviously PC version would have the better controls.
3. Gameplay: I saw some videos of pubg pc and I found out that its actually very hard to get to the top 10 . In mobile version it seems very easy. When I played single for the first time I got 2nd ranking in it. It tries to give us the experience and features as the PC version does. Although it still doesn’t have a first person mode. You can only go in that mode when you touch the aim button.
4. Added new features: In the new update there are some new modes like arcade mode in which there are 28 players in a portion of a map and play area restrict faster than the classic mode. Its good for players who don’t want to spend much time playing it.
Also they added a training mode where you can practice any weapons and vehicles and you will not die in this by other players. You can equip weapons as many times as you can. Although other players just destroy all the vehicles so it is hard to practice them.
Overall it’s a very addictive game which you can also play with your friends. You can enjoy this game anywhere. It is also free so everyone can afford it. Now waiting for fortnite to come for android.
Edit: The latest update has FPP mode and other features like Royale pass, mini zone in arcade mode, character emotes , dancing like fortnite and other cool features and improvements
