Where do you find the lazer sword in dead rising?
Kill 60 within three minutes then look up.
It will be floating on your head.
What happens at the end of Dead Rising 2 is based on what you have done while playing it, so there are many ways how it can end. When you beat Dead Rising 2 you get extra PP but that is also based on how you did. Say that you couldn't afford and Zombrex or find any for Katey, your story would stop and you would on be able to do Psychopaths and find survivors…
search google for a dead rising +21 trainer, you will find a trainer (it's a program that applies cheats to games) use it wisely though, so not to ruin the whole experience of the game. in the trainer you will find a "freeze clock to 7:00" option, use it, have fun killing zombies without being hasty about it.
