Mech Corps is a fast paced, action filled military science fiction story. The world is dying and Space Marines, who pilot giant robot type fighting machines called Mechs, have been sent out to find a new plant for the human race to relocate to. The only problem is that the planet they find has inhabitants that are not open to sharing and are very good at fighting back. This story is filled with filled with gritty action, suspense, aliens, humour, exciting battles and high tech. Each member of the Mech Corps has unique abilities and they work together as a team in order to survive, giving you the feel of what a close-knit military unit is like. As in life, there are some likeable characters and some not so likeable ones in this story. The narrator did a good job of giving all the characters individual voices and making you feel the tension and heat of battle. I enjoyed this fast action story but the two different, yet intertwined storylines could be a bit confusing at times.
