I don't know if this was intended but you do not get the "Escaped From Hell" achievement if you finish the game on hard mode but not on normal mode. I guess one should get both "Escaped From Hell" and "Finish Game On Hard Mode" when this is the case.
List of badges: 1st row-150/200/1000/2500/5000 kills *** 2nd row-10/20/30/45/60 stars *** 3rd row-Complete level 5/Complete level 10/Complete game/Buy the Helicopter/Upgrade a weapon to the max
For those who are having problems with getting badges after last level, just play any other level afterwards and you'll get your badges.
The score scene does not show up after last level so i guess that might cause the problem.
Trading axes for any missing weapon in my armory whenever I can craft'em. You can check my gift-givers on the profile page and see that i've returned the favors.
