H2A Megapack 1.1.2 is live, brought to you by its contributors Raitatsu, Purple Peak1, DocSquishyPaws, Mysterious Ryan, Chaos473, and Yuyuko!

What are HaloCustoms Megapacks?
They are map and gametype packs that make it much more convenient to play and host customs in Halo MCC PC. This pack is for H2A and it currently consists of 84 maps and 60 gametypes. The installation process is quick and simple. Note that this is not the type of game modification that would get your account banned and you may still safely run MCC with Easy Anti-Cheat enabled.

How to Install
To explain very briefly, drop the game variants and map variants into the folders seen below and you should be done. See the included "Install Instructions.txt" for full instructions and troubleshooting.


Updates to the H2A Megapack
Updates to this pack will be slow going due to various H2A bugs that make it harder to make progress or find maps. Announcements regarding future updates to this pack will be made on r/HaloCustoms and the HaloCustoms Discord. In our Discord, you can report any issues with the pack, get help with installing, request new additions to each of the Megapacks, and play in regularly hosted custom game lobbies.

Map Categorizations and Descriptions
Our Megapacks use a map categorization system that makes it easier to find certain maps, using the tags explained down below. To find the matching gametype to a particular map, make sure to read the description which should indicate it, along with the recommended player count.

BTB = Big Team Battle
Includes maps built for large team competitive play,
and more often than not, they support other
competitive modes.

FF = Firefight
Includes maps that simulate Firefight.

INF = Infection
Maps built for infection. Includes linear maps (sequenced
levels like 5 Levels of Terror from Halo Reach), roaming/holdout maps
(open maps where you choose where to hold out), driving maps like Run and Joyriders,
etc. Any map that uses an infection gametype and doesn't
deviate heavily from normal infection (like minigames) have this tag.

MINI = Minigame
Maps built for various minigames. This includes anything
from Hogs from Heck to Duck Hunt to Crash-Up Turby to Beer Pong.

MISC = Miscellaneous
Maps that are either hard to categorize or very unique in how they play.
It includes roleplaying games like Cops & Robbers, School and Hot Pursuit.
It also includes maps that are competitive, yet deviate too much from core gameplay
to be put in other categories, such as Heist maps.

OBJ = Objective
Maps that are built to be used with objective gametypes
like Invasion and Assault. Map examples include Castle Wars,
Bunker Hill, the LOTR series, typical Invasion maps, etc.

OBST = Puzzle / Parkour
Maps for puzzle solving and obstacle courses. One example is Indiana Jones maps.

RACE = Race
Maps made for racing.

RACE BT = BattleTracks
Maps made for gametypes such as LaserSnipes, Rocket Hog, etc.

SLYR = Slayer
Maps built for small team competitive play, and more
often than not they support other competitive

Subcategories and Abbreviations
There are many tags used to abbreviate relatively popular gamemodes such as Duck Hunt (DKH) or Hot Pursuit (HP). This is done so that we can change the names to better indicate which map is which, since having five Duck Hunts named Duck Hunt isn't convenient. When the H2A Megapack is expanded more, this section will be updated to include all abbreviations used.
