there is this video which a guy finishes all stages with all characters to unlock handcannon, but he didn't get 60000 fast to get 5 stars fast, he took more than 3 hours to do it, i think it's possible to finish it in 1 hour or less if you take 2 minutes to get 5 stars in each stage

there are some videos which players try to get 5 stars in 2 minutes in few stages with few characters, the strategy is awesome

it would be good if re4 leaderboards has "mercenaries any%(finish all stages with all characters to unlock handcannon)" and Individual Levels(they could use it as training)

another category i would like to watch is "killing all enemies(like 1200 kills)", i've heard a guy saying that it is possible to do 1200 kills, but i only managed to do 900-999 kills in ps2 version
some enemies spawn, some enemies despawn, this way you lost some kills
