Wow, hope the fact they added the N64 maps in the PC/PS1 campaign means that they take a similar stance with Powerslave and include both the PS1 (which was already there in the free alpha release) and Saturn campaign (but separate in this case, they can't be combined in that manner as they're not completely new, just the same campaign fitting with each system's strengths with differences like the difficulty, level layouts and the ability to bomb-jump on Saturn which is missing on the PlayStation).
