Forum:Shadow the Hedgehog - multiple acts?

So, I added the missing stages from Category:Shadow the Hedgehog stages to that category. I noticed at least a couple of the stages not listed said they had 2 acts, so I changed them to one. However, that got me thinking: should acts refer to the number of missions in the level in this game, or will the acts always be equal to one? Just figured I'd double-check. I'll probably go ahead and update some of the level articles; at least those that are missing infoboxes. --GVOLTT 13:37, March 29, 2010 (UTC)
