That was epic as hell!
This was incredibly well done. The humor is sewn into the concept itself, as a terrifying bloodthirsty Pikachu leaps off a blood-stained wall as it calls out it's name all cute-like...but it was really well shot for a flash.
Most other flash authors, even JohnnyUtah, have a tendency to keep things in a profile view, as if shooting a play on a stage. You displayed an array of shot diversity in this, and it translated beautifully. I was most impressed by the dynamic angles like the Charmander ambushing the entire squad before getting gunned down.
You can really tell you put a lot of effort into this. The soundtrack was perfect for the suspense, and you chose the appropriate sound effects for everything suited. However, the Counter Strike voice clips are a tad dated, and lacked diversity. You could've obtained much more flexibility with the dialogue if you had voice actors on bored...more on that in a bit.
The flash in itself was short and sweet with a good ending (with a hilarious twist ending...I seriously laughed out loud). My only REAL complaint is the lack of a replay button or, at the very least, a preloader with a play button so it doesn't just loop.
Keep up good work like this and you'll be the new legend in our midst...I voted 5!
In the future if you require voice talent, audition me, and I'd be happy to lend a hand! Once again, keep up the great work!
