brief campaign? : Only if you don't play the game properly.
I don't mean that its one of the greatest games ever, but that the sheer size and feel of the planet you run around and the aliens you fight is so huge that the only way to sum it up is 'epic'.
The way your character 'Wayne' runs and controls takes a little while to get used to, it feels a bit sluggish at first. But this only helps to make everything seem as large and on a huge scale as it is.
You'll run and shoot your way through 10 stages (11 including the boss) and each of them, though similar, brings a new set of challenges, as well as the usual blow-up-everything-you-see gameplay that is at the core of each level.
The snow covered levels can begin to get a bit boring and samey by the time you reach the end of the game, but they do enough to try and distract you by throwing in VS suits and indoor/lava levels.
If you've read reviews for this game already then you'll know that its supposedly quite a quick campaign and not too difficult.
I don't think so.
Yes, you can complete this game quickly if you choose to simply run past all your enemies, killing only the bare minimum to be able to advance and get to the end destination as quickly as possible.
But if you want to properly experience this game and give it justice, you'll have to repeatedly do sections over to find the best route to take to get to the end without being shot down by the snow pirates hidden behind walls and ontop of bridges. KIlling the majority of your enemies can get very tricky but
play the game this way and Lost Planet will give you well over 10 hours of fun, sometimes frustrating but in the end rewarding gameplay.
