1. Explorer Same as a scout but with 3 moves andthe ability to see through any obstacles that normally block sight. Comes in the late medieval (perhaps navigation, depends on new tech tree. 10 strength, +50% against barbarians. 2. Balloon A new unit, the first flying unit in the game. It can't attack and is always killed by any interception from AA or other air units. It does have a long range recon ability. This way it can be used to scout into the territory of other civs or just keep a check on your surroundings. It can also be used for exploration by basing it in far away CS. Every time it does a recon flight it has a small chance to totally disappear. This unit comes in the early rennaisance. While the explorer is able to explore uncharted territory anywhere on the globe, it's sight radius is not so big to make it optimal for scouting out neighbouring civs. The balloon is perfect for this goal, as it has a large sight radius and can't be destroyed untill fighters/aa comes around. The balloon isn't very good at standard exploration because it needs a city to be based in and can't collect ruins. 3. Commando Comes around the WWII period. Weaker than units of it's era, relatively expensive. 4 movement total. May move after attacking. Ignores ZOC. Pillaging doesn’t use movement points. Ignores terrain movement costs. Is a scout and gets scout promotions. This unit is best at getting behind enemy lines, pillaging and distracting forces. Or trying to get artillery units and such. Too expensive/weak for direct combat. 4. Great Explorer Like with GG points, you gain GEX point by discovering tiles that were previously undiscovered. The GEX has 3 moves, a very high sight radius and a very high retreat chance. It also ignores ZoC and gives adjacent units +2 sight. It also gets double yields from finding Natural Wonder, City States and barbarian camps. When it takes a ruin you get two ruin bonusses instead of just one. Like all GP it has two unique abilities: * Mapping: This explores a very large radius around the GEX (15 tiles). The GEX is expended. * Outpost: This improvement has no special yields but it has a sight radius of 7. It might also help with espionage in some way. The GEX is expended. When focussing on exploring you will easily earn a GEX, it will help you explore more and recieve bigger rewards for it or allow you to keep eyes out in your territory.
