Given:
n teams
n keys
Start of round:
- give a random player of each team a key (if a team is without players yet, continue waiting), but do not show the key to others yet
- wait some time for preparation (about 10s maybe?). In that time, only the team mates know that they have the key. The enemy gets a message "Scanning for enemy key tracking signal..." in the meantime.
- make key visible to everyone (add waypoint sprite above head)
If a player owning a key dies:
- item gets dropped and still sends out signal
If a key gets lost (lies on the floor for too long or ends up in nodrop):
- Last owning team loses the round
If all keys are owned by the same team AND the key carriers are close enough to each other:
- That team wins
At end of round:
- Winning team stays alive, losing team all respawn (?, maybe not)
- Keys get redistributed (as always, the actual distribution is hidden for some time, only the key carrier himself knows and maybe his own team too)
Scoring:
- Frag: 1pt
- Key carrier frag: 2pt
- Collecting a key: 3pt -> total 5pt for stealing a key
- Winning a round by capturing all keys: the winners gets 100pt distributed among them
- Winning a round because another team lost a key: 100pt get distributed among all winners, however, key carriers among these winners get preferred (like, 100-keycarriers*10 pt among all, additional 10pt for each key carrier)
To make it playable even for "noobs", I would add some waypoint sprites:
- Enemy key carrier: ATTACK
- Team mate key carrier: PROTECT
- Team mate key carrier if you hold a key and all keys are in your team: GO HERE or something like that
- Lost key: COLLECT
One should note that this idea only works on large maps if teamplay should actually happen - dieselpower would be at most a 3on3 map for that... but it would work on any huge DM map. Even MikeeUSA's maps may be useful for this...
But, big problem: how to name that mode? And what are the keys?
As for graphics, the keys could be the rune model from runematch - and actually have the rune's effect on the player (but just runes then, no curses - a carrier is already quite handicapped because everyone knows where he is, the keys send out a tracking signal so he gets hunted down and can't camp). Someone can carry multiple keys, just like in runematch...
