As I ask this most dashingly awesome question, I played It purely for the unlocks.
Now from a player perspective, I'm connected to-a server, playing a game, to Unlock X & Y.
When I've achieved these unlocks, where should this Information be purely kept ? On the bloody back-bencher of the server.
Why Is It so Important to ask?
It seems the unlocked Information went Into a save file, this save file was on my xbox. /Small cheer
To NOT KNOW that little-bit of Information, I deleted my GOW3 Beta from my hard drive.
You might ask about "Didn't they warn you" ? No - They felt It best to display this crucial Information on a place where a small "Majority" of people express they're thoughts, the bloody Beta forums.
I got a message telling me to come play the beta, but I realized that would require me to play a GoW game again. And really, I'd rather watch Starship Troopers again.
