How to boost: Fistful of Frags - unlock Overweighted

Payfire Rewards give £0.50 for the achievement "Overweighted" in Fistful of Frags.

However this achievement is a pain in the butt to get. Butt I have a solution to LEGALLY boost yourself to get it, just follow these steps:

1- Press "Create a server", set the password to something random, so no one will guess it (you don't want to be interrupted to get free money).
2- Set the bout count to 15% and the difficulty to low.
3- Now run around the map gather weapons till you get overcrumbeld.
4- kill the bot 10 times.
5- ???
6- Profit!

Trust me it works, I did the last 4 kill this way (the other 6 where luck).
