When sandbox was first being released everyone was super excited about killballs. and now, a couple months after the release I haven't used them once. we only use them for aesthetics, so this is a killball brainstorming thread: lets take advantage of this awesome and unique item. ideas~ area where you are blind: killballs below a platform. death pit in the middle of a main floor map. unclog feature in a trash compactor map.
Use it for an impromptu death barrier? Also, make the flag spawn point hovering inside of a tunnel pointing downwards into a killball, and below that the normal part of the map. To get the flag you need to either sacrifice a guy or send someone with a bubbleshield to make a safe passage. An underneath 'ocean' of killball-iness that's a quick shortcut to the other side of the map, but to get across you need a bubble shield (several if you elongate it?).
You can place weapons or items very close to it so that you would need to take precautions to grab said weapon. You can make them spawn in random locations in a map to cause havoc for a brief moment or close of areas of the map so that people can commit suicide instead of being locked inside. you can make a small map with kill balls in the center and people have hammers and can try to push people into the kill balls with the hammer.
that gives me a good bumper cars idea! you could make a large platform in the sky bubble and make a kill ball, shield wall, kill ball pattern all the way around. then the players spawn with invulnerability and hammers. there are also gosts that they have to "bump" others with.
Kill balls are annoying because they make that awful sound whenever you get close. Really they don't belong in a competitive map unless you want to make some sort of death hole on the main floor.
I made a map, called Death Pit, in the mini games section, where u have to throw your opponents into a kill ball in the center of the field with gravity hammers or golf clubs. Here's the link if you wanted to see: http://www.forgehub.com/forum/mini-game-maps/65432-death-pit-v2.html
I don't know, maybe like put a killball at the end of a passage way, put a rocket launcer in its depths, and make it so you can only have a bubble shield to get it. That is all I got, its late, post more in the morning
