D2F - Changes

Spring

There is grass outside.
Hardly deserving of its own section...

Fireplaces

Located in the flag room.
If you touch one, you will begin to pee in it.
There are 4 different colors of pee, depending on your condition.
If you pee in one in the enemy base for over 5 seconds, it will refill your health.

Sentry Guns

Sentry guns leak gibs when damaged
If heavily damaged, they appear darker and tilt to one side
When you give a sentry more health (via upgrade or repair), it will love you for it

Teleporters

Teleporter entrances have arrows indicating which direction they will send you
The length and size of the arrow shows how far it goes
A tail on the arrow shows how far up or down it will send you
Enemies as well as friendlies can see the arrows

Pills/Bucks

Bucks are a simple number game for fun, and double as currency.
Commands: !give, !Bucks, !hud, !pubBucks
If you kill someone in their base, you will get 70% of their Bucks, plus 1
If you kill someone in your base, you will get 29% of their Bucks, plus 1
You will get 33% of a persons Bucks plus one for killing their sentry.
You will get 10 Bucks for suiciding while infected
You will get 100 Bucks for capturing the flag, and 20 for touching it.
You will gain 100 Bucks for completing a hunt, and 50 Bucks for foiling one.
If you go for three minutes without a kill, you will lose half your Bucks every minute.
Bucks are redistributed to everyone when you are idle, or when you !give them away.
You may use Bucks to purchase stuff from ralphy (see below)
Betting is currently disabled

Hunting

Commands: !hunt, !tscore
After you complete or fail a hunt, you must wait 2 hours until you may hunt again.
When you start a hunt, you will have 5 minutes to kill your victim.
Your victim's name, health, and location will show on your HUD for the duration of the hunt.
You will get another hunt if your victim leaves, changes team, stays dead, or hides in respawn.
You will fail your hunt if you are killed by your victim, switch teams, leave, or run out of time.

Bridge Gods

For every enemy your team kills on the bridge, your team gains a point.
Backpacks will rise from the side of the bridge credited, and an explosion will show, that will progressively get bigger.
Once you get 25 points, your score is reset to 0, and each member of the team is given 50 points of health, each enemy is reduced by 20.
Note that the enemy score is not reset as well. Scores are reset at the end of the match.
From time to time, a health refill will be available in the center of the map, which appears as a floating blue healthkit

uNFing

Commands: !unf, !tscore
After you uNF someone, you must wait one hour before doing it again, unless its been 24 hours since your last one.
The server will keep a running total of how many people have uNF'd you.
If you uNF someone for the first time, you will score a deflowering.
Players explode hearts when they get unfed, and drip hearts for a bit after.

Ralphy

Commands: !beer, !bagel, !pizza, !weed
Ralphy is the server service bot, he hands out random goodies and insults.
If you ask Ralphy a question (beginning with 'ralphy'), he will answer you up to 6 times.

Cookies

Previously, lyrics or other lines will display on the bottom of the HUD, and if you named the source, you could get a cookie.
Currently, you have a chance of getting a cookie if you switch teams to help balance them/improve match quality.
Cookies are completely pointless, except as an icon next to your name on the stats page.
