Today marks the announcement and release of XCOM's second batch of DLC, "Second Wave," on all available platforms. The new content comes via a free update, adding multiple new options designed to appeal to players looking for a new and different challenge. Specifically, the update adds a new menu of options that significantly alter the way XCOM is played.
Damage Roulette, for example, gives all weapons a much wider range of damage - potentially stealing a killing blow or possibly bestowing a last ditch pistol shot with extra punch. Another option, Not Created Equally, gives all rookie soldiers random stats, while Hidden Potential causes stats to increase randomly with each promotion. Firaxis designer Jake Solomon tells Joystiq these options allow for more versatile soldiers, even some that go against the grain of their classes. Heavies with incredible accuracy? It could happen.
The goal in creating Second Wave, he says, was to offer experienced players more extraterrestrial bang for their buck. "One of the values we offer people who play our games is [that] we really want to reduce the dollar cost per hour spent on our games. We want to consider ourselves to be one of the greatest game values that there is."
Furthermore, many of the new options make XCOM much more difficult and demanding, something fans of the original game are sure to appreciate. Marathon, for example, makes the campaign take much longer, confronting players with higher costs and longer research periods and soldier healing times. Diminishing Returns, meanwhile, raises satellite construction costs for each satellite built. You know, because they didn't cost enough already.
Some options are available immediately to new players, while others are unlocked by completing the game at different difficulty levels. Again, The Second Wave is available today on Xbox, PS3 and PC, so get to cracking some alien skulls. See the full list of new options below.
