Door Blimey, Guv'nor

All of the secrets - most of which are secret levels - in Ducks are accessed by getting the green leader duck to a hidden doorway. Please don't read on if you want to find the secrets on your own! OK, for all of you having trouble, the doors are situated in the following locations...

Level 19: Modern Technology

There's a small ledge in the bottom, right-hand corner of the level. Teleport the leader onto it and then walk towards the cliff face.

Level 29: Over The Top

The doorway here is trapped inside the lump of earth in the top, left-hand corner of the level. Use balloons to blow up the earth. The doorway (which is still invisible) will fall onto the grass below. Now, walk the leader under the area you just blew up. If the leader doesn't vanish, the door's still stuck in the earth above, and you'll need to blow it up a little more.

Level 46: Night Vision

The secret doorway on this level is positioned on a ledge to the left of the two chains on the right-hand side of the level. To get there, you'll need to bridge over the large gap across the bottom of the level. Cross the bridge and then create another, beneath the two chains, leading to the bottom of the ledge.

Level 52: Closing Time

Try and fry the leader with the second of the three electronic duck zappers at ground level.

Level 71: Moviedrome

The secret doorway is located between the two short stumpy streetlights, next to the left-hand rocket.
