I try to experience all a game has to offer before I review it, which in the case of Medal of Honor Heroes meant cutting the multiplayer to what I read on Gamespy (My PSP refuses to connect online in my house, so multiplayer games are out). As far as the single player went, I mentioned that the game consists of three campaigns, each sporting five sub-missions. When I had written the review, I had completed two of the three campaigns, and three of the five missions in the final campaign. 
 
I'm kicking myself for not noting this in the review, but Heroes' most impressive visual effect is in the grenade-daze that shoots up when a grenade goes off right next to your character. Your vision is hazed and blurred, and in the heat of a firefight can cause a quick game-over. As the final levels progressed, I managed to find myself in quite a sizable firefight, during which the game suffered no loss in frames per second.  The final two levels did disappoint me, however. The penultimate level had me tasked with assassinating high ranking Nazi members, who were actually weaker than their lower
 
I did, however, find it odd that either my guns are incredibly versatile, or despite the German depot consisting of MP40's (9x19mm Parbellum), StG44's (  7.92X33 Kurz) and Karbiners (7.92x57mm IS), the Germans seem to carry a lot of Thompson (.45ACP), M1918A2 Browning (.30-6 Springfield 7.62x63mm), M1 Garand (same as Browning) rounds. This is just me nitpicking, but I do remember in Medal of Honor titles of the past, being forced to relinquish my own weapons when ammo and dead allies became sparse, in favor of the German weapons that came with the power of refilling my ammunition. Sure, it felt unpatriotic to not just go in fists-a-blazing, but what can you expect from a Private?  
 
The biggest issue that really turned me off of the game was the frequency, in the last campaign at least, that enemies had of spawning two feet in front of me. Literally, as I was looking in their direction, and in one case the guy spawned on top of me as I was passing by. Forget the fact that the game was spawning enemies in dead-end rooms I had already cleared out, I'd be fine if they just didn't spawn while I was in the room.  
 
I also had a chance to try out the game's skirmish mode, which is similar to a faux-multiplayer. The game lets you go up to 15 bots, but I would not recommend this as, with the AI's unique tactic commonly called "standing in the open and firing wildly," the bots tend to spawn inside of one another. They do offer a better challenge than the AI in the single player game, however, and if you don't have access to the online multiplayer, at least extend the life of the game. In addition, you are scored with a similar ranking system based on your score.  
 
For what it's worth, Medal of Honor Heroes was enjoyable taken as-is. Not the greatest game on the PSP, but something I can feel comfortable displaying on my shelf with my other games.  And yes, I do intend on buying Heroes 2 to review, I have a few other PSP and PC titles that are asking for my attention at the moment.
