Dead Rising 2 : Off The Record is a reinterpretation of the game with Frank West from the original Dead Rising as the main character instead of Chuck. The games takes place in Fortune City, the same place as the Original Dead Rising 2, and features some new locations. Dead Rising 2 : Off The Record revolves around the same main characters and offers a gameplay experience identical to the previous version. with the exception of the new Sandbox mode.
The game concept stays the same if you play the story mode. You have several days days to survive, you should secure a Zombrex for each day while completing missions, escorting survivors to the same safehouse, and making new weapons.
Photography is the only visible change in the story mode. Take Horror, brutal, or hot photos to score some extra PP and level-up faster.
Sandbox mode is a little different, there is no story, survivors are hostile, and there are much much more Zombies to make the journey worth your while. The goal is simple, kill more zombies to unlock more challenges, finish these challenges for cash rewards, spend the cash to get more deadly weapons.
I have made a short gameplay video, featuring the first couple of hours of Dead Rising 2 : Off The Record SandBox mode. This game may not be the best zombie PC game around, but it will give you a few hours of fun.
