How do you create your own game type in Halo Reach?

Answer 1

first you have to go into Custom Games and choose a game type from the type that you want (eg. Slayer or Juggernaut), so If you wanted to make a Slayer game type, just choose, like, Team Slayer or something. Then when it goes back to the main custom games menu press "X", then just go through all the different stuff and change what you want.

Answer 2

Put all the stuff needed for each gametype listed below (quote form Bungie.net)

Each gametype supplies a label that can be used in conjunction with the "gametype-specific" setting that you can use to make any object only appear in a specific gametype. This label is typically the same as the name of the gametype (e.g. "ctf" or "headhunter").

Generally things you label should also have the "gametype-specific" flag set on them, otherwise they will spawn in other gametypes too!

Assault

"as_bomb" - REQUIRED - bomb spawns here (team-specific, can be neutral)

"as_goal" - REQUIRED - plant bomb here (team-specific, can't be neutral)

"as_res_zone" - respawn zone (influencer) which is active when your team's bomb is not planted

"as_res_zone_away" - respawn zone (influencer) which is active when your team's bomb is planted

Note that you CANNOT plant a bomb on the as_goal object if the team that owns that goal is not active in the game (has at least one player).

CTF

"ctf_flag_return" - REQUIRED - flag spawn point and return point (team specific)

"ctf_res_zone" - respawn zone which is active when your team's flag is at home

"ctf_res_zone_away" - respawn zone which is active whne your team's flag is not at home

Note that flags will not spawn for teams that are not active in the game (have at least one player).

NOTE on respawn zone labels in Assault and CTF - these only work as intended when applied to one of the respawn zone objects. But objects with these labels are always turned invincible and can never be picked up (if they are weapons).

NOTE on one-sided Assault and CTF variants - the red team is always on defense in the first round.

Headhunter

"hh_drop_point" - REQUIRED - a place where you can drop skulls

Infection

"inf_spawn" - nothing special (we used this to distinguish spawn points that are infection-specific)

"inf_haven" - REQUIRED - a safe haven.

Note that humans spawn at "red team" spawn points and Zombies spawn at "blue team" spawn points.

Juggernaut

nothing special

King of the Hill

"koth_hill" - REQUIRED - the hill!

Oddball

"oddball_ball" - REQUIRED - a ball spawn point

Race

"race_spawn" - nothing special

"race_flag" - REQUIRED - a race checkpoint. Use the spawn sequence to set what order you have to hit them in. You can have more than one checkpoint with the same spawn sequence, in which case the driver can hit either one to get the checkpoint.

"none" - will get deleted

Stockpile

"stp_flag" - REQUIRED - a flag spawn point

"stp_goal" - REQUIRED - a flag drop point (team-specific)

Territories

"terr_object" - REQUIRED - a territory. Note that the spawn sequence MUST be set to something other than 0.
