I think that is just a case of messing with gametype options to make the player damage higher. As for hydra lock-on... I don't think so.
Currently working on a remake of the CS:S classic minigame, 3k_smash. Got the basic layout going (moreso than the video shows, its a bit behind), just need to figure out how big each platform will be and also some scripting weirdness. Once I've got that done I'll move onto adding the end game gamemodes. For those who don't know, this is smash. Skip ahead like 1 minute: The map throws blocks from the middle onto the arena, which is all posied to fall. You either survive 2 minutes or (in this version) can jump to the middle to get a helicopter which can also drop blocks.
oh wow i literally just found out that was the answer right before i read this but thanks and i also found out if i change it back to no teams it will stay as a player
Emissive overlays got updated in the patch. More color options, and the intensity was adjusted to make for more gradual changes instead of going from 0 to blinding.
I'm sure there will be a REQ pack released at a later date which contains more levels of blindingness.
