This game is unplayable because of the mandatory "unity web player" thing that isn't supported on any browser, and can only be installed in old computers :/
That moment when you spend the biggest part of the day fighting that 3v3 team on the castle but can't win because one guy one shots everyone (on top of having 100% accuracy, since he is, you know, a bot).
On the challenges each medal needs certain points... Like this: Bronze (750 pts) / Silver (1000 pts) / Gold (1300 pts) / Platinum (1800 pts) / Hope this helps!
I still think that the medium badge should be instead impossible. Since you cant ever find all of the clues in a level. Never. I mean... 3 hours straight playing the same level gets kinda boring.
I really think that on all maps there should be only one single specific spawn point for teams... because like everyone knows the spawn points in all the game and camp on them... that already got way too annoying...
