I've beaten
Medal of Honor Vanguard is a WWII FPS released in 2007. You play as James Keegan, a member of the 82nd Airborne as you take part in the various operations the real Airborne underwent during the war.
Vanguard was conceived as a cheap side game for the lucrative PS2/Wii market while the A-Team worked on (the fucking amazing) Moh Airborne so both games share a lot of similarities. Both game stars the Airborne and feature most of the same campaigns (though as the real Aiborne didn't participate in a lot of missions, this was inevitable), both have the mechanic of jumping out of a plane and sterring your parachute - but while Airborne has this for every missions and it had genuine depth in allowing you to land anywhere and complete objectives in any order, Vanguard only has it in three levels out of nine and its very linear level structure means it doesn't add much beside hunting for the one secret spot. Like Airborne, you have weapon upgrades - but while Airborne has three levels of upgrades for each weapons, including each three types of grenades, Vanguard only has two upgrades period (a drum magazine for the Thompson or a sniper scope for the M1 Garand), which don't persist between levels.
One thing Vanguard has Airborne doesn't is the medal system [well technically it does but not in the same way]. For each missions, you have achievements for a variety of task (using every weapons available in a given missions, getting X numbers of headshots, beating a level without dying, etc.) and some of them actually grant you very slight bonuses to your health level, sprint recovery and health regeneration speed. I found this a pretty addictive mechanic and it's rare FPS incentivise completing a level without dying so that's pretty neat.
The game is a very typical modern FPS: you carry two weapons of your choice and grenades, you have regenerating health, and you can lean and crouch/go prone. Levels are very linear and have you doing typical millitary shooter stuff like clearing room of enemies or planting charges on anti-aircraft guns (you do a LOT of explosive planting). None of the missions until the last two are very long or difficult. There are some vaguely inspired scenarios like one part where you have to run around streets scavening ammo for your bazooka while a Tiger tank takes potshot at you, but few and far in-between. If you've played any WWII shooter, you've played this.
Ultimately I enjoyed Vanguard despite its lack of amibition. It plays pretty smooth. The controls do the job and the leaning mechanic is well-implemented: being able to peek out of corners and raise your head slightly while prone without exposing yourself is something often lacking for WWII shooters and it's appreciated here. For Kraut-killing fun times you could do a lot worse - and a lot better.
