It is interesting how physics and movement are implemented as an extra level of skill rather than just to move faster. Learning how to move better to outplay my opponents was something I found really cool in the non-mobile cods, and it was fun trying to implement those skills into this game.
The gun mods, customisation and camos are also great, but there seems to be a small few meta guns that the top players use, and the weapon levelling system is too grind, making it very difficult for a casual player to get the best weapon mods.
Overall, I think it's a great game to try if you are looking for a good mobile fps game.
