Siege is a gametype as in JK3 [Jedi Academy] where BLUE need to touch the RED flag. No BLUE flag exists.

Configuration:
Gametype - CTF (g_gametype 7) or CTY.
Timelimit - 1 hour (or more) (timelimit 60).
Recommended capturelimit - 3 (capturelimit 3).
Force - small rank (g_maxforcerank 150).
Force - enabled all (g_forcepowerdisable 0).
Weapons - enable all (g_weapondisable 0).
Bots - 1 red, 1 blue, 1 red spectator [placeholder], any additional bots (addbot Lando 5 red 0 Lando ; addbot Lando 5 blue 0 Lando ; addbot Lando 0 spectator 1 placeholder).

BLUE must have more players then RED because BLUE missions are very hard.
Why need 1 blue? Playing bots amount must be equal. Why need 1 red? Map timing system (see below).

Of course, you can set other configuration, but it will cause errors. Change gametype - no flag to capture. Smaller than 1 hour timelimit - map timing system error (see below). Enable jump, speed, protect or rage (maybe push, pull or grip) - let players go near the kill systems and not to disable them. All force must enabled! Or no force boons will spawn! Disable weapons - some spezialisations will be bad.

Recommended mod - NT Andromeda 7.

Map missions for BLUE:
1) Unlock ATST - take the imperial key.
2) Destroy the generator - make a beam driving ATST.
3) Capture RED flag.
RED members can't do anything of these missions.

Map missions for RED:
1) Don't let BLUE team unlock ATST - protect the key.
2) Don't let BLUE team destroy the generator - protect ATST.
3) Don't let BLUE team capture RED flag - protect it.

Kill systems:
Auto cannons [2] which shoot a blaster bullet (20 hp) when a BLUE member goes to it.
Cannons for bases protect [2] which shoot blaster bullets (20 hp) very fast when anyone stays behind it.
Laser beams which all [5] kill you except red base beam. Almost all [3] can be disabled. 1 can be enabled by taking the imperial key.
Generator. Shoots lightning harmful for BLUE only.
ATST. Can shoot blaster bullets (20 hp) very fast when anyone stays near the ATST turret. Can shoot laser beam to generator (10 hp). Can kill you when is locked or already made a beam.

BLUE spezialisations:
Sniper (disruptor, seeker)
Rocketer (merr sonn, sentry)
Heavy weapons (repeater, FC1, sentry)
Protector (bowcaster, demp2, all inventory)
Imperial (blaster pistol, rifle, field, bacta)
No miner because he can blow up himself and fly.

RED spezialisations:
Sniper (disruptor, seeker)
Heavy weapons (repeater, FC1, sentry)
Rocketer (merr sonn, sentry)
Protector (bowcaster, demp2, all inventory)
Miner (explosive weapons, field, bacta)
No imperial, have cannons instead.

Map timing system:
Must be a red player which starts when game starts. He must be never kicked. He must not change team or disconnect. Very likely it is a bot. After 59 minutes from map start a message (1 minute left) is shown to all. Then 30 sec, 10 sec, 5 sec. After 60 minutes from map start this bot teleports to a closed room with 1 red and 1 blue flag and captures 20 flags. So RED win if timelimit hits.
