Modders have uncovered hidden multiplayer gametypes in the Modern Warfare 2 source code.

Aparently some multiplayer gametypes either weren't done in time or they were only meant to make debugging fun, but the listed gametypes aren't finished yet. A full description is added to the original post over on Raiders Game net that you can read below.

While looking through some of the ripped MW2 files, I noticed 4 new gametypes:

arena = Round based 1 flag gametype. Basically a flag spawns in the middle, and both teams have to capture it. It's similar to gtnw, except it's the round based (one life) version. A team wins if they capture the flag or kill everyone on the other side.

gtnw = Global Thermal Nuclear War = Basically the "nuke" is in the middle of the map, and both teams have to try and get it and set it off. It's a respawn gametype. You have to first "capture" the nuke, similar to capturing a flag on domination. If there are more axis players inside the capture zone then allied players, then they will capture the nuke and vice versa. It doesn't speed up the capturing if more players on your team are inside the zone. Once you have 'captured' the nuke - it can only be activated if your team score is above 100. You get 1 point for every enemy you kill, and 1 point each time you "capture" the nuke. So if you go and hold the nuke point, you'll "capture" it, then if you keep control if it, you'll slowly gain more points every few seconds. The team who activates the nuke, wins. If the timelimit is reached, then the team with a higher score wins.

oneflag = Basically round based CTF with 1 flag, so Axis defend while Allies attack. If round time limit is reached the defenders win, if flag is captured the attackers win. If defenders are all killed, attackers win, and if attackers are all killed defenders win. Basically it's like retrieval.

vip = Basically it's like assasination. It uses the defenders CTF flag spot as the 'extraction zone' - and picks a random vip... the vip spawns with riot shield and deagle, and also has armor vest and final stand. Once the vip reaches the extraction zone, they have to press use to call in an extraction pickup. This takes 45 seconds, and after that time, the attackers win. The defenders win if they kill the vip or if they kill everyone on the other team. Attackers win if they kill all the defenders, or extract the vip.

I've looked through all 4 of them and noticed they're not fully completed. Well they would work, but they just need tweaking a little. They left a bunch of printLn() stuff which they'd probably need to remove, and they left a line that initializes the _dev.gsc script (a script only for developing).
Although it's probably because whoever coded them was either busy or rushing and didn't notice the minor mistakes they made... (not errors, just extra parameters that don't get used anywhere)

They also found an awful lot of 'TODO' comments in the programming code, and three of those have 'fix after ship' added to it as can be read in the original post by novemberdobby ».

There are ways to play these gametypes but only with a hacked version of MW2 which we will not cover. They can be found via your favorite search engine, but please be advised this could mean being VAC banned from STEAM — leaving you with nothing but trouble. On the other hand, we don't know if these gametypes will ever see the light of day on either the PC or console versions... It's up to you!

Thanks Mr. F!nch!
