Title Update Settings

The title update settings page allows you to edit configuration data made available in Halo: Reach Title Update 1.

The fields available to edit are as follows:

Shield Bleedthrough
Determines whether damage "bleeds through" player shields. For example, if you have 5 points of shields and are hit with an attack that does 10 points of damage, bleedthrough would result in you losing all of your shields as well as 5 points of health, while a lack of bleedthrough would result in you losing your shields but not losing any health (i.e. you receive 5 points of damage and the other 5 points are discarded).
Activating Armor Lock doesn't shed stuck grenades
Determines whether activating Armor Lock will cause you to shed any grenades that have been stuck to you, preventing them from killing you.
Armor Lock can be stuck with plasma grenades
Determines whether plasma grenades bounce off of a player that is currently using Armor Lock, instead of sticking to them and killing them.
Enable Active Camo modifiers
Determines whether the "Active Camo Energy Curve" values are used.
Must have an Energy Sword to sword-block
Determines whether players can survive an Energy Sword attack by using a melee attack with any weapon.
Enable full-auto Magnum
Determines whether players can fire the Magnum full-auto by holding the trigger.
Precision Weapon Bloom
Magnify or diminish the amount of bullet spread and reticle "bloom" applied to precision weapons when they are fired rapidly.
Armor Lock Damage Drain
Taking damage while using Armor Lock can drain Armor Lock's remaining energy.
Armor Lock Damage Drain Limit
The maximum amount of Armor Lock energy that can be drained by incoming damage.
Active Camo Energy Curve Min
Scale Active Camo's energy usage.
Active Camo Energy Curve Max
Scale Active Camo's energy usage.
Magnum Damage
A multiplier applied to the Magnum's damage output.
Magnum Fire Delay Multiplier
A multiplier applied to the delay between firing consecutive shots with the Magnum.

Additionally, there are controls at the bottom of the page that can be used to rapidly apply values from official game variants.

Imprecision

Due to how these values are encoded in game variant files, there are precision limits that come into play when saving and loading. This means that after saving and reloading a game variant, you may not see the exact values that you originally entered. The following technical details are provided for reference purposes, but all that one really needs to understand is that there is a margin of error that may range from 0.8% to 4% depending on the values one wishes to use.

The precision limit, or interval, for Magnum options is roughly (10 ÷ 254), or about 0.04. The precision limit for all other options is roughly (2 ÷ 254), or about 0.008. Some math is done during encoding and decoding to ensure that the minimum and maximum values are always represented with exact accuracy, and to "center" other values within their allowed ranges. This means that the lowest non-zero value will be equal to half of the interval.

As an example, the lowest values that can be encoded for non-Magnum options are:

This also means that the value 1.0, used for vanilla settings, can't be represented exactly. The closest you can get is 1.0039, or 100.4%. Coincidentally, the margin of error in this case is identical for both Magnum and non-Magnum options despite the different intervals.
