*un-sarcastically* Yipee! A 10-shot, semi-auto, maverick-sized blaster made by NERF (so it won't break after a few days of play).
True, this will be little to no use in a typical NIC-style war. The noise of the flywheels also means that it will be somewhat difficult to use in any situation where stealth might be required (i.e. many indoor situations). However, the fact that there is now a NERF-made (rather than BuzzBee) semi-auto flywheel pistol means that a particular playstyle that I have been wanting to try out is now not only possible, but potentially very viable.
One of the games we play at the indoor wars I participate in is a "King of the Hill" game, where stealth is pretty much useless, and everyone is making a ton of noise anyway. I am seriously considering getting a pair of these if and when they become available here in the US, so that I can dual-wield them during such rounds. The only things that I'll be facing that have a larger ammo capacity than the Barricade are RF20's and LSs/Recons/Raiders/etc with 18 or 35 round clips. All of these require more priming time and most are also larger - giving me a potential edge.
I think I'm more excited about the Barricade than I am the Stampede...
