[Ends in 7 hours] Defenders Quest 66% off at $5 but don't buy through Steam. There's a better deal!

Buy Defender's Quest

If you buy Defender's Quest here, this is what you get:

• Steam key.
• Steam trading cards.
• GoG key.
• GoG extras.
• Desura key.
• Soundtrack.
• DRM-free version.

The dev said it's unlikely to be cheaper than this for a while, so get it while it's hot - and while you can recoup some costs while trading cards are still selling high. :D

It also has Steam workshop integration now with a free parody mod campaign. You can download the (lengthy) demo through Steam or play it in your browser on the dev's website. Play the demo

Keep in mind that there's two halves of the game, Normal and New Game+. NewGame+ adds a bunch of sidequests, additional story and new enemy types. There's a lot of value for your dollar here.

Tip: If you just want to get through the game as fast as possible, go to Options -> Accessability and turn EXP/Scrap up to 300% and Failure/Absence to 0%.
