when the round ends, the money rewarded is calculated by the total damage dealt, the remaining life, and the round won bonus..
what i did is repeated round 1 a lot of times (really, like a LOT). then, i maxed out the life of my people. if i get 5k, i buy another person and max out his life too. if you do that, and you finally have 6 guys with maxed out life (their accuracy doesn't mater), just a round of level 1 will give you at least 12k!!!
that's how i got rich and bought all the weapons =))
please keep this comment alive
this is such a sad, yet amazing story. i was touched by the story and how it ended. a very great story in a very fun game. these games should have a separate category. 6/5 =)
for nobslayer, after you find all the evidence, use the computer (you should buy it) and email the governor. then a random number code will be sent to you. then all you got to do is type that number code to the governor's code (the blank space when you are trying to find the evidences)
