Pit People

Perma-death is a campaign mode added to Pit People. Essentially, when a fighter dies in battle, the fighter stays dead forever and cannot be re obtained. Losing important story characters in Perma-death will cause the file to become incompletable, but not unplayable. Only if you lose all of your fighters does the file become unplayable. In order to start a game with the Perma-death option, you must start a new file and confirm that you would like to have Perma-death activated. The game does allow you to skip the intro cut-scenes and fights, putting you right into the city with 6 characters (1 of which you have to go to your house and buy the 6th slot and equip the 6th character).

The easiest way, that I found, to win 20 battles with Perma-death activated, was to go into a private VS. match and invite a friend (who is also on Perma-death). Both players should ready up, the game will start, and then one player forfeits, instantly awarding the other player the win. After 20 times of being brought back to the pre-fight lobby, readying up, and forfeiting, the achievement will unlock. This took about 15 minutes for me and my friend to get the achievement and the process was practically effortless.

The hard way to do this achievement is to leave the city after starting a perma-death file and fighting single groups of enemies and then heading back to the city to heal. This method is time consuming as some groups of enemies are incredibly annoying and large. There is also no guarantee that you won't lose a fighter during the process. (If this is your only option to get the achievement, I would recommend that if you lose a fighter, to just erase the file and start a new perma-death file. You can instantly spawn in the city in the new file with a full team and start doing more battles). Generally battles using this method were lasting somewhere up to almost 10 minutes and the added stress of having to make sure no one dies, on top of the fact that all of the characters were low levels, made it much more difficult than it needed to be.

Based on that information I would highly recommend the Vs. forfeit method. It will save you a lot of effort and time. If you don't have any friends who own the game, I would suggest either setting up a boosting session here on TA or using the "# want to boost" feature, to see who is interested in boosting the game.
