Devil May Cry 4/Resurrection

Underground Laboratory
Head through the door at the bottom after picking up the blue orb fragment.

R&D Access
Through here is the introduction to the Cutlass, another one of Agnus' annoying demons. There are three of them in this room, which is shaped like a letter u. There is nothing of significance here so keep going.

Game Room
This is one of the more fun sections. When you enter the room a silver model of Nero emerges from the floor and a giant dice drops from the roof. The idea of here is simple, get the Nero counter to the end of the board to proceed. The different coloured panels on the floor give different effects. Blue ones are beneficial, giving red orbs. Red squares are bad and generate enemies or some annoying lasers that chase you around. Yellow squares jump you across the board, but can also send you backwars. White squares do nothing. On Son of Sparda some of the white sqaures are covered with a purple design, which warps you off to fight Bael again. There is also a divinity statue at the end of the room but it is sealed until the game is won.
