1: A lobby if people don't want to talk ingame.
2: A upgrade tab whenever you enter ingame. With the upgrade tab you can make a sniper scope for rifle(7 kills required) a better sight for the machine gun(10 kills) and a lesser bullet/pellet spread for the shotgun(12 kills)
3: Friendly mode. A mode in which players don't have guns at all, can socialize, build whatever!
4: A friend option. You can use this option to add friends, join a friend's game, or check their status, or even player profile.
5: Awards/badges. With these you can unlock stronger blocks(Harder to shovel/grenade down), unlock new gun upgrades, or unlock new titles when you chat, for example: THE Awesome EXAMPLE.
6: A graphics changer, like very low, low, medium, high, ultra. Some people like me have good computers that still enjoy the game. It's just that we sometimes like bigger graphics.
7: Explore mode: you have 1 shovel, 1 pickaxe, block building tool, and a rifle. In this mode, you have very limited ammo, and block placing limit(250 blocks only). You can build fortresses, explore RANDOMLY GENERATED land, make friends, or kill random people.
8: More or less fog option. I personally like the war fogs, they look adventerous! They look cool to!
9: 3rd person view. You can turn to 3rd person view to look around you, or just to place blocks easier.
10: Armor or skin customizer. You can stop looking like everyone else and enjoy looking the way you want! I like the green and blue skins, they look cute, but I always wanted a ghille/sniper suit to fit my war looks.
