Grenade Parts Guide

Payloads

The payload controls what exactly happens when a grenade explodes. Most unique grenades use unique payloads to implement their behaviour. Payloads also determine if child grenades are supported – even with several bonuses, none will spawn if the payload is incorrect.

There are 6 standard payload types. In TPS, each of these has a duplicate which can also shatter air masks, meaning there are to a total of 12 non-unique payload parts.

Inventory Balances

The Inventory Balance defines what parts a certain item can have. Balances themselves do not affect stats, but are they very important for the actual generation of items.

Grenade Definitions

Like the name might suggest, the definition essentially defines all the unique properties of each grenade type. There is one standard definition used by all non-unique grenades, while most unique grenades use their own unique definition.

Definitions are very important if you’re trying to calculate exact stats, but otherwise can be mostly ignored.

Expand

To start with, they define the base values for all stats stored on the grenade. Unlike with weapons, this is simply done using regular pre-add bonuses, so see the full parts reference for details.

They also define all grade bonuses, and how exactly they get converted into standard bonuses. Definitions do not necessarily define all grade slots, if a slot’s undefined then no grade bonuses will be applied to it.
