to get the "finish the game" medal, you have to play the game all the way through and beat the boss without dying. Whenever you take more than 100% damage and die, that's when you get the overdosed ranking
Reviews for "Pothead Zombies"
great game
really fun
amazing
fun and exiting but not immense if we could have more zombies (hippys) to kill more levels and passably and auto-save this game would be perfect.
also i had a bit of a lag problem and graphics toggal would not go amiss.
Pretty good.
It was a very fun, if familiar, defense game with an actually useful partner. The problem is, I took a star down because I beat the game twice, and still didn't get the achievement for finishing the game.
5/5 9/10
I finished the game twice but still didn't get all of the medals. Amazing game though.
