So, I guess you don't want to bring up the vehicles or the gunstaff...
Ok first off I stated in the middle of by post that Jak has other weapons, vehicles and gadgets that didnt make it in this game.
As for the Gunstaff that was featured in Jak and Daxter: The Lost Frontier which was a spinoff made by another company. Naught yDog worked with SB to give Jak almost everything he had from Jak 3 and down, maybe Jak X Alternate costume(which im hoping for)! TLF wasnt made by ND so that gunstaff never actually existed.
Yeah despite missing some of those gun mods and even some being nerfed Jak still play really well. However I do wish they added that cool sound effect when Jak lands his Dark Bomb in this game, maybe they added it in the full game.
I know what sound your talking about. Thats an amazing idea I mean I could hear his Dark Jak transformation sound so Dark bomb should have its impact sound to.
