1. SCE's: The two uhm.. firebullet guns (Overlords site) and probably the mythical Blade gun.
2. Battery Check
3. Probably JJ1, or you wouldn't ask this.
4. Probably Bjarni Cool

6. I'm not sure what you mean. Can't you be a little more clearly? I don't know in what order the events should be. If I understood it well, it's probably an event that slows down your movement, like a suckertube.
7. Getting more ammo than 50 (Checked, not copied)
8. An annoying program that annoys you.
9. Servers with a uhm... weird version number
10. No idea. Wakeman? No, that's a staff member. Newspaz?
