First of all Project Evo is hands down the best clone of Rust, atleast in terms of gameplay. Probably this game has one of the most intense, hardcore and unforgiving game environments I've ever seen. Unreal engine 5 is clearly showing its capability for creating mobile games through this game. This game even in the beta stage has some impressive graphics especially when it comes to vegetation and godrays. It is very well optimised and the graphics can be reduced to the least possible values from settings and hence even low end devices can run this game without much issues.

i really want this because been something just like the game rust but just on mobile

If you don't know about this game than you are not a gamer.This is great game similar to rust. We all know that rust is officially announced for android but this game is best but due to budget and some other reasons it has been officially shut down. All the gamer miss this game and hope that this game will return in future.
