Not as much exploration compared to its predecessors which is a little disappointing. Most levels only have 1 path which makes them feel smaller and shorter. I felt the weapons kind of made up for that though, It has the best ones out of ps2 trilogy. There's literally a gun that shoots black holes! Getting them isn't hard either since they're more generous with the bolts this time. There's somewhat of a difficult spike near the end but it isn't as bad as the previous games.
