For the lazy people who want the survival badge without playing, buy the random weapon box and the unlimited ammo upgrade. Launch survival, if you have grenade launcher, just aim the three mushroom spot, put something on your mouse and come back 20min later and here is the badge (you can play for hours like that x)!!!!
i put a 5star for encourage you to improve next episodes or game :). The idea was here, but would love to have an upgrading shop :). For player who always complain, try to make a game before crying this game is not so good as other games!
For killing boss easier, go in low lvl of evil cave, switch between two screen until you meet bahumot, kill it, and have a RS:bahumot, wich give nice buffs in one turn!!! (don't defeat monster on screen, or no more monster will appear!). Good luck ;)
