Medieval Rampage 2
Game Location: http://www.newgrounds.com/portal/view/512758
Sol Location: In the 512000 folder, NG specifically "512758_Medieval_Rampage___The_Rea.swf" subdirectory.
Edit:
The save file, if you've saved ingame in the first slot, would be SaveFile1
There you may edit any value you want, including kills, money, lives, experience, ammunition, upgrade points- you know the deal.
Once I manage to edit it to achieve everything I'll attach it here unless someone beats me to it. Hop to it!
