How to join sandbox?

Tribe mode is that same exact thing.

Sandbox was the old Tribes mode. Now both are sandbox with one having castle building options too.

it says the sever is dead

First, I don't see how this has anything to do with the question and you should post it outside this question, but to answer you then that means that the server has been up for some time and has disappeared for some reason (new update, bug, etc, etc ...)

BUT IF IT WAS SANDBOX MODE EVERYTHING WOULD BE FREE BECAUSE SANDBOX MODE IS WHERE YOU HAVE INF FOOD WOOD WATER GOLD AND OTHERS SO THAT ISNT SANDBOX MODE SO HAHAHAH WANDERS CREATOR MAKE A SANDBOX BUTTON WHERE EVERYTHING IS FREE AND YOU CAN DO IT BY YOUR SELF OR WITH FRIENDS OR ONLINE SANDBOX HAHAHAHAHAHAHHAH NOW DO THAT LOLOL P.A DO IT

uh are you sane buddy?

...

I mean I agree and don't it would be nice to be able to play by your self but I would want to learn what's best to do and not have every thing free

i would just like to say...THEY SHOULD MAKE A PRIVATE SERVER OPTION

plus other players kill me before i have the chance to set a camp :(

YEA SANDBOX MODE IS WHERE U HAVE INF STUFF

Yes they should make a private server mode and a group server mode so there are a total of lets say 20 people or so and allow people to make clans and have a max of 5 people in their clan, this would be awesome to add, please consider
