So for the younger players and even some of the older players (who have been playing this game for a couple months.) You may wonder, "what do I level up in a giga?nothing seems to go up lots". Well don't you worry I'll tell you what to level up and why. Level up a giga's Melee damage. The reason is it's a percentage based stat and with a giga doing massive damage with leveling damage up by even .5% each time is enough to make a huge difference by the time it's max level. Trust me here damage is what you want.
I dare you to raise one!! They are savage if you got two high lvl parents (about lvl 140ish) and you get imprinting on it. The thing will become an adult with about 230% melee and basically one chomp any bronto!!! But on the down side you loose your job and your girlfriend
