Does anyone know what the maximum score is per level? Or, if possible, let me know what the highest score possible for each category per level is that would really be nice (ie. enemies killed, kill bonus, accuracy bonus, health bonus, exploration bonus).

I know the highest difficulty bonus is 5000 for Hard and shot accuracy is 100% but I am trying to figure out which opportunities I am missing out on since I haven't reach 750 kills or 50 pistol kills. My total kill count is 677 and I have finished the game on all levels. I even have the journalist and bookworm achievements as well.

I hope these last two achivements are not out of reach for me, that would stink really bad. Thanks for any help guys!

try to get as many kills as possible, I think u get extra bonuses for high kill counts.Look for places that enemies keep re-spawning for a while.

A good place to bump your kill count up is the first level...when you get to the Gatling Gun...mount it and stay on it...as many as 50-60 men will come around the corner of the cabin in the distance ahead.

When u say first level do u mean for the north side....i'm still having difficulty getting my last achievment as well.
I guess i'll have to play all over again.     

Yeah. for the north.

I know a lot of ppl have trouble getting the General achievement, but I actually got it w/o really trying. I had the General & Pistol achievements only to get and was working on the pistol kills when I got General (and I was playing on easy at the time too--to make getting pistol kills as easy & fast as possible)

I'm sure you don't need to start all over. Try this...you can start off on that first North mission...as you play a level, always hang out in every area you're in until no one else shows up. You'll probably be surprised by how many guys do show up if you wait around. For instance...right where you first spawn in that level...look in the distance in the fields to the right. A whole bunch of guys will keep coming one after the other for a fair amount of time there. Then, as I mentioned before...the gatling gun you come to shortly after crossing the bridge is a great kill increaser as well. Enemy after enemy will keep coming there for quite a while.

Always look for enemies on the periphery of an area you're in. Like the field I mentioned above. There are a bunch of places like that in the game. Guys running down distant hillsides, etc. That sort of thing.

Hope that helps.  ;)

that actually helped out a lot.   thank you.  i actually started on the north side and at the 3rd level in the trenches.  just sat back and kept killing people outside of the trench.  by the middle of the trench i had gotten the last of my kills i needed for the general achievment.  i can't believe just how easy it came up.  i thought it was gonna take forever.  but it didnt.  again i really appreciate the help.

Cool! You even got it on the first level you tried for it on.

Thanx for the reply. It's nice to hear that I helped.
