Quickmatch now supports scripts, including chat commands.

The XP multiplier affects unlock rate. At 40% XP, new unlocks occur every 20 minutes.

These options are entered in the campaign name e.g. Campaign0 (FOV)
(FOV) - Enables limited field of view on difficulties other than Veteran.
(XP##) - Sets starting XP, where ## is the amount e.g. (XP500) = 500 XP, (XP2.5K) = 2,500 XP, (XP1M) = 1,000,000 XP.
(RP##) - Sets starting RP. Number works just like with (XP##).
(UA) - Unlocks a ton of things. Currently, research items (including enemy-faction weapons) have to be researched (or force-unlocked) as well. I might try to fix this later.
(MAP#) - Sets the starting map, where # is a number from 1-10. The usual starting map (Keepsake Bay) is 2.
(MAPR) - Chooses a random starting map.

These do not currently function in quickmatch except for /unlock<faction> commands.
/unlock - Forces the next set of timed unlocks. Forced unlocking is not saved/loaded.
/unlock5 - unlock x 5
/unlock10 - unlock x 10
/unlock50 - unlock x 50 (there are less than 50 timed unlock levels in total, so this unlocks them all)
/unlockrng - Unlocks rare items obtained via briefcase/vehicle deliveries, (and some other things like faction-specific vehicle flares, due to how locking currently works behind the scenes).
/unlockenemy - Unlocks enemy-faction weapons (by forcing the research, persists between saves/loads).
/unlockall - /unlock50, /unlockrng, and /unlockenemy in one command.
/unlockgreen, /unlockgrey, /unlockbrown - Unlocks enemy-faction weapons (does not persist between saves/loads).

/cd - Resets all radio support and vehicle drop cooldowns.
/acd - Resets all radio support cooldowns. Note that vehicle drops called through the radio use vehicle drop cooldowns.
/vcd - Resets all vehicle drop cooldowns.

Just about every single weapon and item of any use now has its own spawn command. Things can have multiple possible spawn commands so you don't have to remember the precise name. As an extreme example, the Golden AK can be spawned with /golden_ak47, /goldenak47, /golden_ak, /goldenak, /gold_ak, /goldak, /auk47, or /auk-47.

Throwables like grenades (/frag) or ice cream (/icecream) are added directly to your inventory.

DEPLOYABLES
Deployables can be spawned, both in normal and quick-deploy variants.
/dc, /qdc - Cover Deploy
/dmg, /qdmg - MG Deploy
/dminigun, /qdminigun - Minigun Deploy
/dgl, /qdgl - GL Deploy
/dtow, /qdtow - TOW Deploy
/dhornet, /qdhornet - Hornet Deploy
/dmortar, /qdmortar - Mortar Deploy

ARMOR
/demigod - Demigod vest (invincible like God vest, but no movespeed bonus)
/unicorn - Unicorn vest (invincible, fast, and invisible to AI)
/vest1, /vest2, /vest3, /exo, /eodvest, /ghillie, /blackops, /camovest
For the can-respawn-with variants, add an r at the end e.g. /vest1r, /ghillier

XP/RP
/promote##, xp## - Adds XP, ignoring the XP multiplier. Accepts inputs like /xp1.5k for 1500. Not entering a value uses the default 4000. Negative numbers can be used to remove XP.
/rp## - Like /xp, but for RP. Not entering a value uses the default 500.

ENEMIES
/grunt, /grunta, /gruntma, /gruntmb, /gruntmg, /medic - Spawns a rifleman, assault (armored shotgunner), marksman A (long rifles), marksman B (battle rifles), machine gunner, or medic. Add an e in the front (e.g. /egrunt) to spawn an enemy. Add two e's if you want the second enemy faction on the map (crashes if there is no second enemy faction).
/eod, /eodmg - Spawns an EOD (shotgunner) or EOD (machine gunner).

VEHICLES
Most vehicles now have spawn codes. This is usually the vehicle file's name. Faction-specific vehicles (e.g. different variations of tank) are just the normal spawn code with 1 or 2 at the end i.e. /tank, /tank1, /tank2.

Vehicle flares can be spawned by adding f at the front e.g. /ftank.

/fieldlab - Spawns a Field Lab.
