I have my Beta Testers which most of them have helped me since the first Betas (and by the way, two of them got modded, so I guess it's a good charm :P), usually with three people (and me) I consider it enough. In the end, once it is released people will surely come up with unexpected stuff no matter the ammount of testers... jojo! >o<
I always use a piece of script (which, as usual, may contain parts that are garbage, but since I dont care much about investigating, I dont mind it)
#raw 0x2F
#raw 0x4B
nop
setvar 0x8004 0x0
setvar 0x8005 0x3
setvar 0x8006 0x9
setvar 0x8007 0x2
special 0x136
pause 0x1
Pretty much the setvars, the special 0x136 and the pause are what's necessary (with some of the setvars you can control the strength and duration of the quake), go ahead and investigate it on your own because I dont remember which var does which.
