At roughly fifteen dollars, there was so much to do that Orcs Must Die! 2 was a very good value. It gave you plenty of maps, traps and modes. So when an expansion pack was announced for it, we posted about it here and got some good questions about whether or not the new content would justify the five dollar cost.
First, here is what Fire and Water gives yout:
* New Levels to Defend – The fight for survival isn’t over yet! Battle your way through three exciting new levels in single-player or co-op – Traffic Jammed, Double Decker, and The West Wing.
* New Endless Mode Conversions – Think you’ve mastered Endless Mode? Think again! The Fire & Water booster pack features three new Endless Mode level conversions to hold your ground on – The Library, Double Decker, and The West Wing.
* Terrifying New Enemies – Prepare for a whole new challenge when you face off against the harrowing new Fire and Water Elementals!
* Exciting New Traps – Add some deadly new defenses to your Spellbook with the Web Spinner, Ceiling Darts, and the Floor Portal!
* New Bonus Skull Definition – Can you hold the invading monsters at bay without traps? Prove your mettle by playing exclusively with weapons and you’ll add another bonus skull to the pile at the end of each level.

My verdict? If you are a huge fan of the original and just want another reason to go ahead and kill some more orcs? This is an expansion I had no regrets playing. If you are just a casual fan who only loads it up once in a while, there might not be enough meat on this particular piece of DLC to justify it being one third of the actual game’s price.
hmm. I still haven't bought it. Robot Entertainment's way of padding (and also supporting) the game with further dlc is generally not a problem, but $5 (or rather 5€!) per piece is a bit much. considering this will no doubt be discounted further down the road (christmas sale?) and there are plenty of other great games to play right now (Torchlight 2!), I can wait.
It's a great game, but I think that's a fair assessment too. Likely there will be some sort of discounted Steam bundle for the holidays for those who are patient.
