It's fine the way it is. One buy only. However many detectives you have, that's how many health stations are possible. If you want people to be cautious, add a pain station to your server.
I have a felling you have absolutly no clue what I'm talking about. I'm saying it shouldn't be an instant heal. It's really cheap to have someone able to camp their way to a victory because of the health station.
Really, the health station is really cheap now, you can just camp it and easily survive a firefight. Why not fix that? I suggest adding an effect where your health goes up gradually, and is canceled when you are hit. Of course this would still add 10 hp every time. Whenever you "use" the health station while already healing, it queues up that extra health to heal after the previous healing.
I'm iffy on the fast-paced thing. TTT isn't deathmatch, but this map seems to encourage that. I'll need to play it, but you may want to add some more open spaces to encourage TTT-style gameplay as opposed to DMing.
Yeah, I guess I'll add a courtyard type spot in v2.
So, I felt like making something like dust for TTT, then it turned into this.
TTT_Stone is a medium sized map with many alleys and tunnels. It also has many, many weapons to use. This is my first released TTT map. Download here: v2 has a new courtyard area, as well as some new tunnels to it. (making it actually playable.) There are various other fixes.
