Though we're sold on Chroma's ambition, playing it -- at least right now in Alpha form -- is a mess. Not just because it's early, but also because there's a tremendously steep learning curve. Playing as any of the more advanced classes (engineer, tank) is nigh impossible, as even basic shooting is governed by matching trigger pulls to the beat (we played with an Xbox 360 gamepad, but a mouse/keyboard combo works as well). A visual indicator on-screen helps the rhythmically handicapped with upcoming beats, but even veteran beat masters will have a hard time juggling character control, map navigation, aiming and shooting while at the same time trying to match shots to the beat (not to mention lining up the timing of hitting an enemy with the rhythm of the in-game music).

Beyond being an incredibly risky blend of two totally different game genres, Chroma will live and die by providing a lag-free experience. The game's dependence on rhythm while also being an online-only shooter means that any lag results in an extremely off-balance game. And all it takes for players to walk away from a free-to-play game is, well, anything. It's free, right?

As a veteran of FPS games and a longtime Guitar Hero/Rock Band/Dance Central player, Chroma simply threw too much at me at once. It's hard enough to learn a new level, parse a game type and master basic shooting mechanics without having to also figure out how rhythm fits into that. Frankly put, rhythm is too complex an input to add to a genre (FPS), which is already packed full of inputs. At least that's how it felt after playing a few rounds of Chroma last week. For what it's worth, the reps from Harmonix were all keenly aware of the barrier to entry and assured us that a rigorous training program is being created.

Thankfully for Harmonix, enough good will was built up by past work to give us pause before outright writing this off. We'll give Chroma another shot when it becomes available in closed Alpha this month (sign up right here). Harmonix isn't giving its new game a hard release date just yet, but says to expect wide availability by "this fall."
