This isn't excactly the "ensnared survivor" decoy I was looking for, but it'll do. The only downside is that in regular versus mode, there are no survivor respawns, but only really attentive players would notice.
Pros: I found a great lure in vs. mode, thanks to you. Who'd of thunk that this would work, this is the next FYI I am a Spy. You just need to find a spot, where you know a person will re-spawn, spray it on the outside they walk by see it, assume it's a teammate they open the door and bada bing! Hook, line and sinker, I've added this to my sprays list, time to up the ante on L4D.
Cons: None that I could find, but I'll keep looking.
Improvements: Perhaps a Zoey spray? Or a Bill, Louis? That would be a lot more selective on the victims, that way they couldn't tell to qoute Admiral Aqbar "It's a TWAP!"
Notes: If I find any cons I will post them here. Good job though, I'm glad someone requested this to be made.
