Humanity's final hope

I've started playing Resistance : Fall of man on the PS3 in cooperative, with Tvvity.
The action takes place in an alternate reality, one in which World War II never happened and Lenin's revolution was supressed, leading to Russia still being lead by a Tsar.
The introductive cinematic starts off the story with the news that the Chimera, species created deep into the Russian territory in the 1940's after some biological experiments, have conquered in a matter of weeks the entire Europe, Britain being the last remaining free European country. After some time of fighting, Britain falls too. "The war was lost" - the narrator (a woman) tells us. She then recounts of an attack the Americans launched on the western coast of the U.K., and introduces Nathan Hale, an officer in the American army. She says we'll be following the story of the days of 11'th to 14'th of July, the last day Hale was seen.

I think we've gotten to about the middle of the game (12'th of July) and, up to now, the game is really a hit. The enemies are both varied and clever, making it a joy and a thrill to shoot them out of our way. The graphics are excellent and the sound is very mood-setting and appropriate to the action you are experiencing. The multitude of weapons and enemies makes the game very dinamic, allowing you to choose a number of factors that will contribute to your victory, instead of just going and and thrashing your way mindlessly (although, I must say, you CAN do that, but it takes all the fun out of it - we managed to finish one level in about 2 minutes).
When we finish the game, I'll post a complete review and more pictures.
