this is not worth your money, save it or rent it.
the ds version lacks weapons, multi player, and single player.
the single player falls short on the story and missions. almost all of the missions are the same andthe graphics suck. there are barely any weapons and the guards are easy to get past by. the level design isnt that good. the single player levels are short and the story is.
the multi player falls short. the co-op is the only good thing and there isnt that many co-op levels!!!!!!!!! but the other multi player modes fall short too. and it isnt single card!!!!!!!!! you need two ds and two game cards just to play co-op and multi player!!!!!!!!!!!!!!!!!!!!!!!
this game is only good if its $10 and if you have some one to play with. but then you need to buy two copies.
