Okay, we just finished a Live co-op survival session on Heavy Weapon. In short, Heavy Weapon co-op is fluid, fast, and a hell of a lot of fun. This is great news considering the recent co-op woes of Assault Heroes. Like any survival game, it starts off slow enough, but soon it escalates to the point of sheer insanity. There are so many things happening on screen that it's impossible to keep track of them all. The air is filled with a solid cloud of bullets, missiles, lasers, aircraft, and general mayhem. And it's 'effing awesome. Some will no doubt deride Heavy Weapon for its simplicity, but we praise it for the same reason (and we dig its retro sensibilities). Oh, and if you like earning achievements, survival co-op offers plenty of them. You could easily earn six in one session. Surviving for twelve minutes is tough, but it's made much easier with three buddies (though to be fair we only made it just past thirteen on our first try). For those of you who have Heavy Weapon, give online co-op a try. It's sure to bring back plenty of arcade memories (hopefully memories without the creepy guy who played way too much Galaga).
