Medal of Honor: European Assault places you in the marching boots of one U.S. Army Lt. William Holt, field agent in the OSS. As Holt, you are sent to various locales to ferret out secret information and eliminate those hording the info, if you have what it takes. As such, you'll be working with the various groups of the Allied forces, so you are never with the same group for two missions in a row - a good thing in case they all manage to die. :)
The meat and potatoes of European Assault is the Single Player Campaign mode, which pits you and a team of squad mates against a host of Nazi enemies. At the start of the mission, you'll see a group of eight or so tasks, most of which will be hidden and require unlocking. Your primary objectives will be visible and these are the tasks you must complete to finish the mission. If you like to explore, you can open up additional tasks which reap added benefits at the completion of the mission. These may be as simple as gathering info on a rocket or as crucial as rescuing imprisoned Allied soldiers who will go on to become your squad for that mission.
In addition, there are added objectives in the way of bosses - your Nemesis for that area. These guys are tough and can dish out and take a lot of damage. If you kill them, you complete one more additional goal and they always have the secret documents with them, so that's another goal out of the way. Why bother, you might ask? Depending on what you manage to accomplish throughout a level, you will earn either a bronze, silver or gold medal. Each one yields extras such as additional healthpacks and Revives to carry into the next mission, and these really help a lot.
The implementation of the Revive is a nice feature. These are basically one ups for your level. If you die and you have a Revive, you just get up from the battlefield and continue fighting, albeit your man sure does take his time in doing it. If you don't, it's game over and you have to begin the mission all the way from the beginning. And these are really long missions.
Medal of Honor: European Assault starts you off in an area with a team of three squad-mates (well, it does in most of the missions, anyway) and you can command them using different button presses. Although I recall having a team with me in Medal of Honor: Rising Sun, I didn't really care much about them and allowed them to take the heat until they all died, then I'd finish the mission. Cruel, yes, but fairly damned effective for me. With European Assault, however, I found myself caring for these guys. Maybe its because they had names and I got a message flashed across my screen when they'd die. Maybe its because I had the ability to heal them this go round, but I found myself giving up my healthpacks to keep them going. It just added another dimension to the gameplay.
Also included is a robust multiplayer mode which allows you to play, split-screen, with up to 4 players on one system, more if you have a System Link. I was surprised to see no support for Xbox Live, but actually enjoyed it more playing with friends in the living room, personally. The typical multiplayer game objectives are there including Death Match, Capture the Flag, King of the Hill and so on. There are 15 maps to play across and although the main draw is the Single Player Campaign, I found the multiplayer game modes to be a nice little diversion.
