Heeeeeeeeeey!

I (Peter) have gets this myth suggestion from Birdie:

'Hello. I have a myth for you to bust, We have all fired seekers and pepper spary backwards, But is it possible to fire bouncys and/or blaster shots backwards.'

Well, Birdie: we'll TEST this myth. But BUST this myth immediately is not our way to do our job.

For this myth I have created a small level area that Ischa fill with weapons.
On stage one we have put normal weapons, on stage two all upgrades and on stage three the shields.
We have shooted 3 hours non-stop with all weapons

We have discovered that if you push left and right and you shoot with the Toaster, some flames flies backwards. But with the other ones it isn't. Also with the upgrades is it inpossible. Only with RicoChet-walls you can shoot easilly backwards. (DUH)
If there bounce a Bouncer or a Bubble (from the Bubbleshield) to a wall it will bounce also backwards.

For the rest is this myth Busted.

End result: Myth BUSTED
