If it's crap ... We'll tell you
Now I was a HUGE fan of last year's Transformers: War for Cybertron game. The game had an original story, great gameplay, and awesome multiplayer. High Moon Studios was placed with the responsibility to take that game and adapt it for the movie tie in. Unfortunately, with any movie tie in game, it falls short.
The story is set before the events of the movie and the Decepticons are in hiding. You start off playing as the Autobots, and about half way into the game, you change to the Decepticons. The first gripe I had from the start was no Co-Op Multiplayer campaign. The level design wouldn't have permitted this at all given that you find yourself going backwards past the same areas multiple times. This was a cheap way to lengthen the levels and causes them to become stale very early on. Not to mention the parts where you are trapped in an area and forced to survive waves of enemies before you can move on.
Gameplay has changed somewhat with the inclusion of a 3rd transformation known as "Stealth Force". All characters have both a Robot form, a Vehicle form, and this new form that lets you fire weapons from you vehicles. If you played War for Cybertron, its nothing new, other then being able to switch between 2 weapons in this form as opposed to only having one. The downside to this is you find yourself either using Stealth Force only to move from one point to another. Your Robot weapons can do the job just as well, but without the sluggish side stepping of Stealth Force.
My biggest complaint has to be the multiplayer. It seems that High Moon had to restrict what kind of Customizations you could make to your characters in order to simplify them and make each character unique. There are 4 Classes to Choose from, Scout, Hunter, Commando, Warrior. Although they might seem the same as their War for Cybertron counterparts. They can not be modified as much. Before, you could choose both Primary and secondary weapons, both abilities, and 3 perks that are both shared between all classes or unique to individual ones. Now you can only choose between secondary weapons, secondary abilities, and the same set of perks for all classes. Even more restricting is that Autobots and Decepticons themselves have exclusive abilities. Leading to a forced change in playstyle if you play as different teams.
Other changes to multiplayer are small but subtle. No hit markers to tell if you landed the shot. All reticules are the same for all weapons and lead to confusion as to what you might have equipped. Shared killstreaks that don't offer much advantage. The level design for the maps are very restricted, you find yourself in long allyways trying to speed past 90 degree corners, or trying to fly above the ma only to hit invisible walls that don't lead to any advantage of flight.
Given the nature of Movie tie in games, I didn't expect much going into this to begin with, it still plays better then a generic tie in game given that its cookie cut from War for Cybertrons impressive style. But with so much of the game being restricted to fit its earth setting. It lost its ability to create something unique.
