The Air system was left untouched for balance reasons.

The unlocker skill is a generic, useful to all unit, promotion that slightly increase attack and def (stackable) and raise your %EXP GAIN, making leveling a little less exponential in term of cost and allow a more interesting end game play.

So, available for your first level up is: the unlocker and the former 2 'Basic promotion' of the unit (you start at promotion level 1). Now, every time you level you can buy a promotion of the skill level youre at, or you can buy the Unlocker to raise your promotion level and expand your promotion list choices.

All the 'basic promotion' has been converted into 'Level 1 promotions', All former Vanilla Promotion have been distributed in different Promotion level and many custom promotions were added and distributed as well.

This skill is the 'Unlocker' of higher level promotion. A new generic skill with 3 level has been assigned to every unit.

There is now a 'Promotion Level' concept.

To these basic skill is attached a skill tree who expand as you level one of the base skill.Р”Р‡or example: Drill I - Drill II - Drill III OR Shock I - Shock II - Shock III, would open the rest of the vanilla skill.

Every unit has 2 choice of 'basic promotion' based on terrain type or domain.

Changes the tree system for easier browsing and promotion planning.Expands the promotion system with roughly 3 times the number of promotion available in vanilla for each unit.ThatРІР‚в„ўs how we spell fun at Firaxis Games. If your opponent has a lot of woods or jungle, you might choose Woodsman, or if your opponent is surrounded by hills you might choose Guerilla.Р”Р„ll in all, the new promotion system in Civ IV offers players a plethora of interesting new decisions, excellent customization options, and an extra layer of strategy. Some promotions give bonuses based on the type of terrain in which the unit resides. For instance, Cover gives a bonus against Archery units and Formation gives a similar bonus against Mounted units, while Shock does the same against melee units. Others give bonuses against a certain type of unit. Some are simple like Combat (5 levels), which gives progressive strength bonuses with some extra healing at the top levels, or City Raider/City Garrison which gives the unit bonuses only when attacking/defending a city. The promotions take on many different forms. As you might expect, the first promotion comes rather quickly, while each subsequent promotion requires more XP. In addition, some wonders, civic choices, and leader traits can give units extra experience or even certain promotions. Units can also gain experience from a Barracks (land units), a Drydock (sea units) or a goody hut. Successful combat is the primary means (note: you get more points from attacking than you do from defending) and the units must be victorious in a unit-to-unit combat, therefore there are no XPs (experience points) from bombarding fortifications or if the opposing unit withdraws.

HereРІР‚в„ўs how it works: Units can gain experience points in several ways. The numbers and types of available bonuses differ per unit type and only land and sea military units can acquire them (air units are different). For Civ IV, we decided to build on this system and make promotions much more intricate and customizable by allowing players to choose from over 20 different bonus types (many with multiple levels, for a total of over 40 available promotions). Displays promotions in a tree format either for the current unit or by selecting one of the eleven combat classes (melee, naval, recon, siege, mounted, etc) from a drop-down menu Hooks into the DiploCorner drop-down. In Civ III, unit promotions involved rising in level from green to veteran to elite and each level added a hit point and a small combat bonus.
