Infected is a game about zombies, and while this premise has been done to death and back again, the developers have strived to put interesting and comedic content first. While this does a good job at initially entertaining you, it doesn’t help the fact that the rest of the game is far from funny when it comes to playability.
Planet Moon Studios is the same group of people who brought us the games Armed & Dangerous and Giants: Citizen Kabuto. While Giants was nominated many times for game of the year when it came out, what these games were noted for was their UK-induced humor and how well they pulled it off. There is no shortage of the tongue-in-cheek content in Infected, but where the story and comedy leave off, the gameplay forgets to pick up.
As zombies break loose during the lighting of the Christmas tree in NYC, you get attacked and wake up in a hospital with a severe bite that should have been fatal. This is special because not only are you immune to the zombie disease, your blood is like kryptonite to the undead horde. This becomes your main weapon in the fight against the undead, as you wield a gun that is rigged up to your veins and shoots bullets infused with your blood.
At this point, the game becomes run-and-gun. There are various types of levels including hostage rescue, defense, and kill ‘em all, but it ends up being the same routine over and over again. The faster you kill the zombies and finish the level, the more points and money you get to upgrade your weapons. You also need to finish enough levels in a fast enough amount of time in order to move onto the next. While this is a good incentive to do well in each mission, it can become annoying in the long run to have to repeat levels with the sole purpose of completing them in a shorter amount of time.
Multiplayer, for the most part, is pretty standard. There are the regular deathmatch, attack a single player, and civilian saving modes. The strange bit comes in when you win a Multiplayer game. Upon victory, you "infect" all of the players you defeated. Your character then appears as the bad guy in their high level Single Player missions, and they have to play as your character in Multiplayer missions until they defeat the high level Single Player missions. A nifty little feature despite the fact that it doesn’t affect gameplay at all.
