Astro Tripper came out yesterday, and came complete with unexpected Trophies.  If collecting small lumps of pixels that increase an arbitary integer in your profile lights your candle, then cast your eyes down to these beauties:

Bronze Trophies:

• Pod Oppressor – Destroy 10 mutated pods in any one level of training grounds.
• Spidery Point – Destroy the Spidery Boss on Arachnophobia.
• Tank Oppressor – Destroy 20 tanks in sequence.

Silver Trophies:

• Tank Sympathiser – Destroy both generators on Claustrophobia without killing a Tank.
• Fly Swatter – Destroy 3 Flypods withing 5 seconds on any level of Insect Infestation.
• Sneeky Incursion – Destroy the Boss without opening more than one outer door. Only 1 of the 3 outer doors may be open to any degree.

Gold Trophies:

• Worm Tangle – Destroy 3 Worms in sequence on The Ooze.
• Wheel Collector – Complete level Fizz Wheels without killing a Fizz Wheel (the rolling wheels connected by a laser).
