Hard but highly addictive....
As far as i am concern the starting of game sets the tone for the remaining sequences with you driving into the motherland of the locusts with a whole army. As the counter attacks begins your team mission is differentiated from the rest of the army with your doing the major jobs (as expected).
The weapons are majority the same but there are few interesting additions such as flame gun. As the game progresses the game difficulty level remains the same which is much appreciated by many gamers. Though have to say the difficulty level decreases in last couple of sequences specially the last one. But never the less it was an amazing ride till those sequences even in those last two sequences you get to ride the most dangerous weapon of the enemy and destroy all their bases.
/over all this is the best action game played by me and expect the pert 3 of the series to deliver the same.
