Medal Of Honor : Underground is one of those never get bored of games. With a two player mode you can hone your skills to a tee.
The gameplay is great fun and you feel a real buzz being a new female recruit to the OSS "Manon" kicking some Nazi butt. There are 7 missions over 22 levels.
You don't go it alone the whole way though , on the first level you receive help from codename "brother". This isn't an easy game though and you will be challenged to protect people as well as yourself and some missions are like a maze to give you more fun.
When you have completed the game don't forget to come back here and check out the cheats to go over the game again with loads of fun. Happy playing!
