by the way, don't try putting things from prequels into sequels, it really kinda messes stuff up. I accidentally did that with fuedalism and fuedalism II, it was very interesting.
The link for the site that explains how to do it on windows, vista, and macs, is http://www.lineridershare.com/faq.php It explains how in the 1st question.
You're going to need to paste the save into the EXACT SAME folder that it came from. Then refresh or re-open the monsters den game if its currently up. The save should be there. (If the slot you need to copy to is in use, then i think it MIGHT work to change the number of the 4 things you are copying all to a slot that IS available, i haven't tried that though, but if you need to, go ahead and try it, otherwise you're going to have to chose whether or not to replace the save that is in that slot.)
obeliskos, i actually know how to do that, cuz im smart like that. ok, so pretty much ur gonna want to go to where you save the files at. On Vista (it's real similar on windows, but mac im not sure, i know a site that explains all of them, i used it to transfer line rider saves)its C:\Users\whatever user you are\AppData\Roaming\Macromedia\Flash Player\#SharedObjects\some random characters\chat.kongregate.com...then you are going to look for where it is saved. For me, its \gamez\0001\0531\live\monstersdend.swf...not sure if its same for every1 for this game. When you open the "live" folder, there will be a few things in there. One is interface.sol, the others will be slot1, 2, or 3.sol. chars, dungeon, inventory, party The things you need to copy are the 4 things applying to the save slot that the party you want to copy is in. What you need to do with those saves is either to e-mail it to yourself, or use a flash drive, etc. to transfer them to the other computer.
I wish that you didn't need to go through 2 times to get diff badges. If you go through on hardcore and beat the corruptor, you should still get Corruptor Disruptor. Thats what i did, but now i have to do it on beginner too. Stuff should always be on any difficulty if its going to be the lowest one.
