secret medals
Most of the secret medals are just a second kind of kill
but the ones that, I guess, are more difficult to find are:
-lose to the fist guy (cowboy)
-when face Hans (black with zipper) wait for him to shoot(he kill himself)
-with Teatowel(terrorist), before click BEGIN, click on his "hat", first no, then yes(for 2 medals)
-Before face Wako(clown), in the scene of choose weapon, seach for a invisible click, then click(duh)
-after finish the game click on any link to other games, not the replay
remembering that some characters have a single way of kill
