Tribes: Ascend

I seriously hope you guys are at least planning to play this delicious game.
It's free, but it's currently in its closed beta stages (I think)
You can get a key by liking their Facebook page, not sure how long they're going to keep doing it though.

But in all seriousness, 350km/h sniper battles in mid-air is a helluva lot of fun.

I remember playing the original - spoiler: I didn't know what the fuck I was doing. Maybe I'll give it another try, it's not every game where fucking jetpacks are considered part of the CORE CONCEPT.

And there's an extra!
The closest server is in AustraliaLand! Now you can enjoy 140~ ping!

That feel when you're going full pelt for the opposing flag and just manage to grab it, but you're going so fast that you end up at the other end of the map, landing you balls deep in enemy territory and eventually getting you mown down by those fucking base turrets.

But do you know what the best part is?
YOU CAN SOMETIMES PARTIALLY SEE THE FLAG ON YOUR BACK.

I might try this, looks fun.

Just 2gb though

Free games are always nice, but I would like to avoid the stalker site.
