In order to get the Handcannon you must achieve a 5-star rating on every level, with every character. The best I ever did was 4-stars for each character on every level. It really is hard. I would recommend either Krauser or Wesker to achieve big points.
I've definately beat mercenaries with 5 stars on each level with each player (trust me, it took me months). And I even got that little message saying "you unlocked the hand cannon". I just haven't found a merchant that sells it yet.
I'll keep on truckin' and hopefully come across it.
You might need to be on your second round on your Professional file. Maybe it will show up with the Matilda and stuff.
I personally have only 5 stars with Krauser and Wesker on all levels. My friend got 3/4 levels done with Hunk (we spent a day taking turns playing Mercenaries). We have like three stars on one level with Ada and one level with Leon. I haven't played in a while.
Yea I'm starting to think that I have to beat Round 1 first. Mainly because I'm halfway through Round 1 on Professional and still haven't found the hand cannon.
I'll beat it and keep you posted.
It's not worth the trouble you go through. Just use the Typewriter machine gun.
In the time it takes to fire the Handcannon twice, you deal more overall damage with the Typewriter, and you don't have to get a 5 star rating for everyone.
The handcannon is just there so hardcore gamers can go "I got everything."
I did everything for RE4 Gamecube EXCEPT 5 star ratings and unlocking the handcannon.
I understand where you're coming from, but I've got everything else in the game except for the hand cannon, so it seems fit to just beat the game entirely and then finally put this game to rest for a while haha.
download the game save from gamefaqs.coma nd transfer it to your memory card.. trust me it is worth it.. you get "EVERY SINGLE THING" in huge amounts... pretty cool playing on professional with that.. .lol
