Mission Evo (Project Evo) is similar to Rust, best mobile clone for rust so far... Been playing since closed beta test and definitely recommend you try it out...

This game is almost similar to Rust

Three days into game and so far I am really impressed. Honestly played Rust and this game is close to par with many individual benefits over it. Considering this game plays on most cellphones and loads ten times faster than Rust with comparable graphics/content it's like taking Rust everywhere with you. (no more being raided while not at computer)
