Set for a release on October 2nd — the same day the standard version also hits — Tecmo Koei have now revealed not just what will be in the Collector’s Edition of Ninja Gaiden Sigma 2, but just how much it will cost.

Bucking the trend of asking gamers to sell a kidney to get their hands on the more “elite” of game editions, Tecmo Koei have announced that the Collector’s Edition of the popular action series  will retail at £49.99 (no word on other currencies just yet) and is exclusive in the UK to retailer HMV.

We guess this is what happens when you don’t have to cover the cost of night-vision goggles.

Here’s what you get for your fifty sterlings.

• A copy of Ninja Gaiden Sigma 2, exclusively for the PLAYSTATION®3 computer entertainment system.
• Limited Edition 80 page ‘Ninja Gaiden Treasury’ featuring:
- Ninja Gaiden Sigma 2 prologue comic written and designed by Team NINJA, which sheds more light on the intriguing storylines of Ninja Gaiden.
-Character and Concept Art Gallery .
- Lite-Strategy Guide including: Weapon Profiles for the 4 playable characters. Combos & Ninpos. Hints and Tips for Story Mode and Team Missions.
- Commentary from Ninja Gaiden Sigma 2 producer Yosuke Hayashi, the Lead Artists behind the game and one final Tidbit from Team NINJA….
• Complete, limited edition original soundtrack CD.
• Exclusive downloadable costume available through the PlayStation Network.

There are some nice additions here such as the exclusive costume and soundtrack CD. However, it does beg the question: with online retailers quoting the vanilla edition at £34.99, is the above worth £15?
