* First time I saw nade spam. (OK it wasn't WTF, it was more like wide-eyed "oooh, shiny!")
* Finding out MD has zoom (the WTF was for me being oblivious for so long).
* Seeing a turret commit TK for the first time.
* Seeing adv basi gas humans through the walls.
* Me as a nooby noob, Mr. naked shotty human, going down the ATCS tunnel. I turn a corner, see a dretch (another newb) coming straight at me, no evading, no jumping no nothing. I stop and shoot it in the face, once, twice, three (3) bloody times. Each time it has amazing pellet spread luck (saw it bleed) and survives. I just stood there gaping and it ran right over me. I was left thinking that must be the amazing powerful rant I'd heard people talk about.
* I was a basi alone in base on ATCS. I hear a human taunting as he comes up the tunnel. Catch a glimpse of him, he's naked. As I casually make towards the tunnel I hear a nade drop, the little bastard has thrown it in and is camping round the corner. So I wait, no hurry, I will catch him and punish him anyway, right? It explodes, I rush out of hiding and walk right into a 2nd nade. This was on a vanilla server, no other human around (only him on radar as I attacked). I never figured that one out. Best I can figure, some very weird lag spike. Lag was otherwise good (ping in the 50) and lagged server.
