Eve of Extinction
Bonus weapon:
Successfully complete the game under any difficulty setting.
Save the game after the credits complete. Reload the saved
game to start with a new double dagger weapon in addition to
your original two weapons at their levels in the previous game.
Survival mode:
Play level 1 and go through the subway when you need to get
both Legacy Drives for the Lightning Rod. When you get out on
the other side, go into the alley that has the fence with a
junkyard on the other side. Walk up to the fence. Press
Triangle when equipped with the Lightning Rod and quickly
change to your hands to grab on to the top of the fence. Jump
over to the other side, then go to the wall that has the ladder
on it. Climb up the ladder and get up to the top of the building.
Once there, you will find a piece of paper hovering above the
ground. Walk into that paper. A message stating that survival
mode has been unlocked will appear. Save the game, then enter
the bonus option at the main menu to access the new option.
3 minute battle mode:
Play the China-town level after getting the Katar. Climb up the
Chinese house that has the huge flame on the porch. When you are
up there, someone will surprise attack. Kill him and go to the
opposite side of the part you climbed up to. Go to the back of the
house, but stay on the balcony. Jump to the building on the far side
(all the way down, as far as you can see) and look around for another
piece of paper. Walk into it, and you will unlock the 3 minute
battle mode option.
