When compared to MW3 it's a loser, but outside of that, winner!
As a standalone, the campaign is one of the finest shooters I've experienced in years, successfully finding the middle ground between a realistic military simulation and a great piece of entertainment. The story, which covers two action-packed days in the US military's ongoing battle against insurgents in Afghanistan, masterfully switches between the perspective of an elite group of soldiers, and the Army Rangers, and offers a genuine, realistic look into the struggles of being a modern warrior.
Some of scripted moments take you out of the game and make it less immersive. The graphics are good. The framerate is a bit shaky, and some of the textures are lacking. The atmospheres are great though, the lighting, smoke, dust and particle effects are all top-notch.
Multiplayer:
The elements that are available in the campaign simply don't exist in its online mode. The way you move through the environment and the way you approach a scenario are totally different. You can't slide into cover, or lean and peek around cover. These two gameplay mechanics, which defined the "uniqueness" the gameplay, are missing, leaving nothing but the framework for a Call of Duty clone.
Online multiplayer in Medal of Honor is an experience-driven, class-based competition. Before each spawn, you can choose one of three classes: rifleman, special ops, and sniper, each with their own loadouts, experience system and level perks. As you earn XP for each class, you'll unlock additional weapons and gear to customize your weapons. Getting consecutive kills and performing any helpful team actions will unlock a series of "tactical support" perks, like a mortar strike, rocket attack, or added armor.
MW3 players will find the frenetic, arcadey, twitch-based shooting familiar. It only takes one or two shots for someone to go down, and respawns are fast and plentiful. It's fun, and I've played multiplayer on B3, MW3, and MoH. Out of the three, I like MoH best.
There are only four gameplay types to play through: Team Assault (Team Deathmatch), Sector Control (Domination), Objective Raid (Demolition) and Combat Mission, an objective-based mission mode. Combat Mission is the most exciting of all the modes, with large maps that really accommodate the 24 player limit well. With combat spanning multiple strongholds, and a psuedo-narrative that keeps it all together, this mode demands the most urgency, coordination and communication for success.
There are only three Combat Mission maps, and only five maps for all the other modes. When compared to the feature set of MW2/MW3, Medal of Honor does lack the split-screen support, any co-op campaign, and there is no "kill cam". For a game with as many deaths as this, it's frustrating not knowing how you were brought down.
Conclusion:
In any other genre, a stellar single player experience would be enough to garner a whole-hearted recommendation. But it's impossible to ignore the importance of multiplayer, especially when Medal of Honor's primary competitors tend to excel at both. Medal of Honor's campaign is an exceptional experience, but the total package simply doesn't beat MW2/MW3.
