Dead Rising 2
#1: Durable weapons - when you get to the mission with drills turn this off.
#2 - Unlimited Ammo does not always work within one region. Change the region and it will work unlimited again for some weapons
#3 - Time Reversal - the biggest headache I had was figuring out not to reverse too much - It can make your game devoid of ANY life and zombies, NPC's, everything. People start floating, switching places randomly a lot...it's a mess. Biggest problem is this so avoid doing this.
Oh and fyi check out DEADRISING2.PROBOARDS.COM for GAME MODS. Great site. Under Mods/Other Mods, check out "DEAD RISING 2 TIMER." Instead of having you forward it / reverse it, this can SCALE back the rate at which time passes, making it slower or faster in-game every second. VERY COOL.
