Upgrade

**Upgrades** are improvements for units. They increase things such as damage, armor, attack/sight range, maximum energy, etc. In addition, some upgrades allow units to use abilities (or "spells") that are not enabled by default, such as burrow, lockdown, psionic storm, etc. See Spells (Terran), Spells (Protoss), and Spells (Zerg) for a list of spells.

Each upgrade's default settings and maximum can be changed in the map editor. An upgrade can range from 0 to 255. For armor upgrades, 1 is added to the armor for each upgrade level. For weapon upgrades, the weapon's bonus damage is added for each upgrade level. The weapon bonus can be changed in the unit settings. For spells and abilities, upgrading past level 1 does not have any effect. (For example: Upgrading "U-238 Shells" for Marine attack range from level 1 to level 2 or beyond will not make a marine shoot further.)

The mineral, gas, and time costs of each upgrade can also be set. "Base cost" is simply the cost of the upgrade. The "Upgrade factor" is added to the base cost for each level of the upgrade.
Upgrades cannot be reversed once completed. Units given between players do not keep their upgrade levels (Upgrades are player-specific).

## "Unused" upgrades

SCMDraft2 and StarForge give you access to a small set of "Unused" upgrades. These upgrades do nothing - exept for the last one, which does quite a lot. The costs of this upgrade are not important as there is no way of buying it during a game. Its use is limited to setting its default values in the map editor.

This upgrade affects the following things. Upgrades marked with an asterisk essentially do nothing. Bonus armor for invincible units and unused units is not useful. Bonus damage for unused weapons is not useful. Also, most spells do not gain any improvements. (A notable exception is the Psionic Storm spell, which gains a damage bonus).

Though this upgrade can be useful, it is important to be careful since it has such a broad effect on a player's units. In particular, remember that all of a player's buildings will get a bonus point of armor for each level of this upgrade.
