There isn't. You could always go back to old areas and kill the little people that spawn there, but that isn't exactly free-roaming. The whole game is a set-Single Player game. I think free-roaming would be fun for Overlord 2, but it was never made.
no it is not
The best free roaming video game Gta4 Red Dead Redemption Saints row 2 and Minecraft that i know of.
saits row 2
Yes Overlord 2 works on windows XP! http://www.amazon.com/Overlord-2-Pc/dp/B001P2M546 for more information about Overlord 2!
To be free
overlord 1 and overlord 2 are equally good not only do the both of them have alternate endings many good levels you will enjoy both o them
Overlord 2 would get you more value for your money but if you plan on eventually getting both you should get Overlord: Raising Hell for it's story.
Go to google and type in "DBZ RPG" its like legacy of goku 1+2 where you can walk around and such... www.planetmado.com is a good online, free roaming dbz rpg.
