Doodle army 2 : mini militia , one of the best game . Size of the gameis less than 100mb so you can say it is light game . It is available on android and ios operating system . You can play it online but you should have internet connection for that or you can play with friends. The concept of the game is very appreciatable.
This game is now routine for me . Me and my friends daily play this game in college or anywhere we meet. There are so many customisation in this game you can change the appearance of your player.
There are so many weopoms like sniper , shotgun , grenade.
You should try this game with your friends.
