Those of you who were fans of Call of Duty 2 or World At War will recognize the World War II relic-style settings of Infection, which takes place in a quiet little French village. There's a lot more openness to this map, especially as you walk through the town right down the middle, so make sure to avoid it if snipers are lined up to get kills. There's some room to run into with the nearby buildings, but you're likely to find soldiers there as well.
There are open ends on either side (mainly for respawns), but other than that, this map is pretty cramped. However, for those who want to get right into the action, it's a great way to jump in. Also, make note of the rock walls lined up with some buildings, as they could save your life if someone is firing upon you.
