I have authored an initial version of this plugin, which uses the following server variables (all changeable in the server configuration, though not in real-time as you play the match):

Code:

spawntickets_marine_tickets	100
spawntickets_alien_tickets	100
spawntickets_warning_percentage 20
spawntickets_skulk_ticketcost	1
spawntickets_gorge_ticketcost	2
spawntickets_lerk_ticketcost	2
spawntickets_fade_ticketcost	3
spawntickets_onos_ticketcost	4
spawntickets_marine_ticketcost	1
spawntickets_jetpack_ticketcost	3
spawntickets_heavy_ticketcost	4
spawntickets_gestate_ticketcost	1
spawntickets_tk_double		1

It operates per the basic design discussed here and only on CO maps. Presently, the plugin pauses itself immediately upon loading and will not affect gameplay at all. To enable it, an admin (not temps, sorry) must enable it using the following command:

amx_on spawntickets.amxx

This will enable the tickets gameplay mode for all subsequent CO rounds on that map. Once the map changes, the tickets gameplay mode is again disabled until it is turned on.

So, to test this out, ask an admin to enable it.

Please pay close attention to how the balance works, and think of ways we can improve it.

So far, it looks like the number of tickets given each team may need to be based somehow on the number of players in the game, as 8v8 will go through X number of tickets much faster than 3v4.

The 'tk_double' option above is a setting which can be turned on or off (the plugin has it off by default, but I have our server configured such that it is ON). When this setting is turned on, team kills cost the team twice the number of tickets that the death would have cost otherwise.

The 'warning_percentage' is simply the percentage of the starting tickets that a team must be taken to before all players will see that team's ticket count display as red and flashing.

Please try this gameplay mode out and provide feedback here.
