As discussed in our interview with Waves dev Rob Hale, the free update containing a new game mode and 28 new achievements was pushed out over Steam last night.

Chase Mode is all about forcing you to keep rolling over a red pad every five seconds, and each time you hit the pad, a new one spawns. You've barely got any time to spare to think about shooting baddies or collecting pickups, since you always have to head straight to the next pad. It's intense, and much more punishing than the other game modes, but stringing together a high scoring combo feels even more rewarding. Top stuff.

If you've not got Waves yet, it's currently got 25% off in the Steam sale, or you can get it alongside some fine company as part of the Awesome Indie Bundle.
