Both the PS2 and to a lesser extent the DS version are middling, basic shooter games. The PS2 being third person and the DS surprisingly being a FPS. The PS2 had lots of charm and gags like any Lego game while the DS was pretty drab by comparison. Nothing remarkable about either version but if your a huge Bionicle fan then there's no harm taking a look at them out of curiosity. Just don't spend a lot on them if you can help it.
