yea this thing is a fucking nuke in midfield clusters if learned right; it took me a while (because it can take damage, and does damage if it hits something it's difficult but you can do a hold-fire-jump and put it to head-height, basically wiping the area clean of enemies)
It's also a sentry killer. Hell, if you can get it in a flagroom and none of the enemies can destroy it it'll wipe the flag room clean. The bots get lucky by jumping (I changed them all the characteristic jumpers if it's present) but a regular player base will just get fried to hell.
Calling it the finger of god is about right.
There's code from q2 based on the laser beam from the BFG I'll use, it's how I did the laserball, it's basically the same thing (linking entities then unlinking them). One damage per beam, 4 beams, rotating about 1.5 times, 6 damage of 30 tops if the player just stands there and takes it.
