tbirdo: That is a weird fricken comment on the 3drealms walkthrough. I makes it sound like there was a version that bundled all the levels together but I don't know of one. Even the PS1 version was episodic. Maybe the 360 version lets you carry weapons over.
HenitoKisou: Because it is xbox version, they already said that in walkthrough but also commented that except few differences in maps their level walkthrough applies to both versions.
Ah I see. I didn't know they still updated the 3DRealms site. I thought this was an old walkthrough.
