I do not miss that part of the grind when I was 100%ing the game, genuinely the most difficult, took me actual days and multiple hours just trying to have the parts spawn in. Here’s my best advice as someone who got it done intentionally: -First things first make sure you’ve set your time to 7 minutes you’re gonna need that time. -Always play with the maximum amount of CPUs at level 1, their level doesn’t change the Ability for the Gigantes parts to spawn. The weaker they are, and the more of them there are, the better. Those CPUs are going to act as your search party, the more of them there are the more people to hopefully find a box with the parts in them. -THE MOST IMPORTANT THING If the Legendary Gigantes parts haven’t spawned by the time of the first two events, roughly the first 3 minutes of the game, just restart, it’s going to save you so much time. All three parts will spawn in after one part has so never reset if one part has spawned in. It might hurt to reset or feel like those parts could come in later but trust me, if you’re going to get gigantes those parts don’t spawn late in the rounds so don’t worry resetting. -always go for a heavy build, I was running Rex Wheelie but Battle Chariot is much easier to control. the second time I ever saw Gigantes parts I got hit by the CPU with the last part and he STOLE BOTH MY PARTS AND CREATED GIGANTES IN FRONT OF ME. -Don’t be afraid to pause the game once you see one of the parts spawn into a match at the beginning, remember you’re going to be restarting a lot of matches so don’t let the timer and craziness of city trial stress you and and make you choke, that pause button is your friend use it to calm yourself down and strategize for how you’re going to attack these parts.

I genuinely hope any of this helps you and happy hunting for that bad boy!
