It has some great ideas, but the single player is too short and the graphics are pretty lacking.
Story: You play as Boyd Travers, a member of the United States Airborne Division. Your character never talks or shows any sort of emotion throughout the game, maybe to make you feel like the main character much like Valve's approach to Half Life 2, this doesn't work well for MoHA though because EA takes no attempt to imerse you in the game as there is basically no dialogue or cutscenes other than mission briefings, soldiers giving you orders, and an after mission report. The game adds a final level which turns out to be a sort of "fantasy setting" where you face off against a giant flak gun tower filled with elite Nazi's who carry around MG42's and can take a full clip of machine gun ammo. This turns out to be one of the best levels in the game.
Graphics: The game has decent graphics with the first and last level looking especially good, most textures are bland or blurry however and much of the character models are poorly detailed and have blocky faces. The guns are well detailed, feel powerful and have fantastic sound effects. There are noticeable glitches though with texture pop ins, especially while parachuting, you can see all the trees and miscellaneous objects poping out of nowhere and sometimes it can take a full 30 seconds for a texture to load.
Gameplay: MoHA plays like your standard FPS except you click the right stick to melee and have to cycle your weapons for grenades. In the beginning of each level you parachute in from an airplane and can choose any place on the map to land. Each mission starts with a set of objectives (which are surprisingly varied) and as soon as you've finished them, you stop parachuting in when you die. The areas with green smoke are the "safe zones" and contain crates of ammo health. You may want to avoid groups of enemies though because they have perfect accuracy with every weapon, which can be incredibly frustrating, especially on levels with snipers. EA included a pretty cool weapon leveling system for the single and multiplayer. The more you use each weapon, the more experience you gain with that weapon which causes it to level up, giving you upgrades that range from larger clips, to grenade launchers. The combat gets intense with Nazi's all on the mindset of "kill you no matter what it takes". If you kill an enemy on a turret, another quickly takes his place. They constantly chuck grenades in your direction, and blindfire from random areas.
Value: MoHA has little replay value (unless you want to go through and unlock achievements and find secret drop zones). There's 6 levels which can take around 6-8 hours to complete. There's a multiplayer that plays really well with one team starting as Nazi's on the ground and Americans air dropping in on each respawn. The same Weapon leveling system in the single player is found here except that each weapon levels easier and the weapon types for each team share experience so if you level up your BAR as an American, your Sturmgewehr will also level. MoHA is probably too short to buy, and not many people still play the multiplayer, you may want to rent it because of low replay value and a dieing multiplayer.
