Commandos 2 is the epitome of the entire stealth-action genre.
How about an ambush with a rifle, a submachine gun, and a few pistols? A few dozen bodies lying on open ground ought to be enough bait...
The Commandos series has long been the yardstick by which all stealth-action games are measused, and the second full game is by far the best. Commandos 2 takes everything that made the original two games fun and accessible, and ptus it together with a fairly cohesive story and tremendous level design that superbly complements the strategic and stealthy nature of the game.
Commandos 2 brings back the Green Beret, the Marine, Driver, Spy and Sapper from the original games, and adds the Theif, Seductress, and others. The slew of characters greatly contributes to the game's feeling of cooperation in pursuit of a larger goal. The game's lengthy single-player campaign is further appreciable with the game's open-ended nature - missions can be completed in any manner you choose - which allows for a great deal of replayability.
In addition to the single-player aspect of the game, Pyro Studios brings back the ever popular cooperative multiplayer mode, though competitive multiplayer is absent until Commandos III. The cooperative multiplayer mode offers the complete experience of the single-player game, but with the added fun of being able to play with a friend. Each of you chooses some of the soldiers present in a mission, and off you go. The cooperative mode adds even more replayability to the already significant amount the game already offers.
Personally, I love this game as one of my all time favorites due to it's stealthy, "Commandos style" gameplay, though my absolute favorite feature is the true coop mode available to people with a buddy who can play with them. Though the graphics are extremely dated at present, nearly five years after its release, I still play Commandos 2 with as much enjoyment as I did when I first bought it at launch five years ago.
