You'd think considering how important they are to the franchise, developer nWay would have included them in the game from the get-go. But noooo; we had to wait for almost a whole year before the giant robots got jam-packed into the mobile fighting game Power Rangers: Legacy Wars.
Well now they're here, and as you would expect, you can pit them against the plus-sized villains from the series' 24-year history. By finishing Alliance Missions, players can collect Zords. Gather enough of the corresponding type and you can unlock the Megazord in question. It kind of stinks when you unlock something that isn't the traditional Dinozord, but having a hulking piece of humanoid metal on your side isn't all bad.
