there is something you can do to prevent jetpacks from complicating your map.... kill zones. but only use when needed
So I was thinking about all of this discussion as I contemplated my latest work, which has very high points that one with a jet pack can exploit, but no one else can reach. I am thinking of using a soft kill zone that provides a general ceiling over the entire map with the intent of (a) discouraging camping on these high points and (b) curbing the use of jet packs. But the problem that I come across for (b) is that they "see" the high points on the map, but don't "see" the kill zone when they have to choose the load outs. Naturally, they choose the jet pack, and then they will get discouraged when they cannot use them to their fullest. I firmly believe that a jet pack (or any other armor ability) should never open any part of a map to a player that cannot be achieved without it. So I am going forward with my plans to create a ceiling and let people with jet packs rethink their plans when they respawn. I know it isn't the best feeling for those who choose jet packs, but it seems to be the only real solution to combat jet pack abuse. I was debating this for some time, thinking that Bungie wanted jet packs, so maybe camping on high points is something they intended and I should not discourage. But that is not a game play design I want exploited on my map. So... it is a sad day when you have to modify your map to interfere with the designs by the game play authors. And today is such a day...
Sometimes it's best to leave kill zones off when there's no cover because people simply bring more attention to themselves up there and are quickly overpowered. The general rule I follow is, if it gives more of an advantage than just flying with the jetpack they already have then it needs a kill zone.
