On the day Bulletstorm launches in the US and three days before it goes on sale in the UK, EA and Epic Games have announced paid for downloadable content.
The Gun Sonata pack includes three new maps for the game's Anarchy mode and two new maps for the Echo mode.
There are also two new Leash enhancements, the Flamingo and the Pulp.
The pack, due out in the spring, costs 800 Microsoft Points (£6.85) or $9.99 / £7.99 on PlayStation 3. No mention was made of the PC version.
Oh, and don't forget, as an EA published game Bulletstorm features the Online Pass system. Owners of a new copy of the game can redeem their code to gain access to six bonus Echo maps and the exclusive Quicksilver leash. Buy a second hand copy and you'll need to purchase the Bulletstorm Online Pass for 800 MS Points or £7.99.
Bulletstorm, from Polish developer People Can Fly, scored a wonderful 9/10 in Eurogamer's hot off the press review.
"This is a game that wants you to laugh so hard that you sneeze on yourself, but it's also a game that wants you to experiment as much as possible with the tools you've been given," Christian Donlan wrote. "Its cleverness is as lightly worn as it is unexpected. It's the best kind of guilty pleasure."
