Revenge offers a non linear campaign, allowing you to pick your missions. Some will require, at least at first try, to play with a certain transformer, forcing you to experience every robot instead of just picking one you like most and sticking with it. This can be a good thing and a bad thing at the same time. Some missions are just a pain in the ass with certain robots, while you can breeze through with others. On the other hand, more experience for you in multiplayer and a more varied singleplayer overall.

But this problem is especially thorny when playing with flying transformers. You see, multiplayer balance applies to singleplayer as well, and having the ability to fly, you trade off a lot of speed and maneuverability on the ground. Not to mention flying bots are not as well armed or have longer cooldowns between weapons fire.

In order to increase your mission performance, there are a number of tokens spread on various locations that can be shot down for an added 10 seconds bonus. Time won't add, but instead the counter will freeze for that period, so don't expect to pick up one and jump back to gold from silver just before the mission end for example. Tokens also give you extra experience, or Energon.

Depending on your performance in the mission, time you pull, bonus objectives and tokens gained, extra Energon will be available to you at the end. This Energon works as I said before: experience. Spend it into one of the three tiers of Hit Points, Cooldown Duration, Special Ability Cooldown, Turbo Boost and other abilities to improve on them. Whether you decide to increase you life or decrease your weapons' cooldowns, you will need this precious resource to make it easier in future missions.

The upgrades window insures enhancements for all of your transformers, and you don't have to individually train and improve each of them.

There is also no customization available whatsoever, you cannot add a set of rockets on a bot's shoulders for example, or a laser gun on the left leg. Just these passive improvements I mentioned earlier.

Gameplay wise, it can be pretty fun to smash army tanks and fight other transformer bots, but you cannot attain true glory until you've played some online multiplayer matches. You can see straight out of the box this game was designed to be a fast paced multiplayer game, and the story is just a pretext for that. Well not that much, because it's based on the movie, but you get the idea.

As for tips, I really liked the story of the little engine that could, when I was young, and in Revenge of the Fallen I enjoyed playing with Bumblebee and Sideways the most. They are fast, deadly, and can really get in and out before you even know what hit you. Plus both transform into speed cars. What more could you ask.

It of course depends on your playstile, as heavy bots have extra damage or splash damage, or can fly. Every transformer has a melee attack, and two different attacks on the left and right hands respectively. When transformed, you can also use the vehicle's gun.

To make controls even easier, LT is used to transform into vehicle mode and accelerate. A nice way for fast getaways, or for quick car-to-bot combos or dodge moves. However, the disadvantage is a poor driving control. You'll smash every tree, road sign and crash into every corner building while getting away without proper brakes and constantly accelerating.
