Infiltration is a unique board game with unusually fast games. I purchased this game after reading a review on Rock, Paper, Shotgun which I would recommend to anyone interested in the game.
The game is set up randomly each round, and the abilities and items for each player are random, which contribute to a strong replayability. The rules are fairly simple and very consistent; there are only a few rare exceptions to the usual round of gameplay and implementing these exceptions is straightforward. The result of this is that outside of set up time, the game plays very quickly. The first round that we played (three players total) lasted merely an hour, and that was primarily due to taking the rules slowly as we learned them. Subsequent games go much faster and can be completed in as little as thirty minutes, depending on how the players approach the game. The game length does not vary much with the number of players, as turns go relatively quickly. It should be noted, however, that you require alternate rules for two person play; Infiltration is meant to be played with at least three players and only improves with the addition of more.
The art for the game is lovely, and the cards are well designed. One complaint is the use of small chips to account for victory points; these chips need to be stored face-down for the entirety of the game. It can be difficult to keep these chips in order without viewing them. Moreover, the chips can have a value from 1-3, and the number of chips with these values is set. This could cause an issue if chips are lost, as they may imbalance the game (though this is not going to be an issue for all but the most obsessive players).
Infiltration is an excellent game for groups of three or more looking for a fast, easy game to fill time.
