To start things off, here's the trailer for Dark Times II: Rising Son:

All that done, let's start this mini-countdown.
Countdown: T-Minus 1 day
What is where?
This will be a somewhat unorthodox countdown post, in that whatever I might have planned to show here went up in acrid smoke along with my modding PC's power supply last night. Fortunately for you, I am hypersensitive to having my ducks in a row as far as mod releases go, and I've had the mod uploaded and prepared for release for a couple days now, so there should be no change to the schedule.

In any case, in this countdown, I want to take the time to point out where you may be able to find certain heroes, units, vehicles, or other aspects of the mod - in case you are the type to hunt down something that seemed particularly interesting to you.
First, we'll go over the heroes. What are our heroes? (Please note that BBY will denote a hero available in the pre-GCW time period while ABY will denote a hero available in the GCW time period.)
Alliance Heroes
Starkiller (BBY)
Galen Marek (ABY)
Obi-Wan Kenobi (BBY)
Rahm Kota (BBY/ABY)
Shaak Ti (BBY)
Bail Organa (BBY)
Yoda (BBY/ABY)
Luke Skywalker (ABY)
Han Solo (ABY)
Chewbacca (ABY)
Leia Organa (ABY)
Col Serra (ABY)
Vace Thermill (ABY)
Imperial Heroes
Starkiller (BBY)
Sith Stalker (ABY)
Darth Vader (BBY/ABY)
Emperor Palpatine (BBY/ABY)
Shadow Guard (BBY/ABY)
Maris Brood (BBY)
Mara Jade (ABY)
Boba Fett (ABY)
Dengar (ABY)
IG-88 (ABY)
Bossk (ABY)
Alliance Space Heroes
Han Solo (BBY/ABY)
Biggs Darklighter (BBY)
Wedge Antilles (ABY)
Imperial Space Heroes

There are also several new units (playable conquest units aside) that are only available in special modes (hero assault, objective, etc.). They are:
Luke Skywalker (Pilot/Jedi)
Kento Marek
Sith Specter
Tusken Raider
Tusken Hunter
Weequay Skiff Guard
Weequay Guard
Young Rancor
How will you know how to see which unit you want? Every hero unit's appearance is, first and foremost, contingent upon the time period being correct. If you are in the pre-GCW time period (BBY), then any of the heroes for that time period may show up. These appearances are weighted, though. On any planet, with the exception of the below-named planets, it is unlikely for Yoda, Obi-Wan Kenobi, Shaak Ti, or Maris Brood to show up. Obi-Wan is more likely to show up than any given hero on these planets - Geonosis, Kamino, or Mos Eisley. Shaak Ti and Maris Brood are more likely to show up than any other hero on Felucia, although they will never be heroes together at the same time. Yoda is more likely to show up on Kashyyyk or Dagobah. On the newer maps in the BBY time period, this same weighting persists (meaning it is more unlikely for those four to show up).
The GCW time period (ABY) is much more equal across the board. There are no subjective weights given to specific units. However, if a unit is available in both the GCW and pre-GCW time period (any of the above listed as "BBY/ABY"), then it will be only 50% as likely to show up as a unit unique to the GCW time period. For example, if the time period is set to the in-GCW time period, Luke Skywalker and Mara Jade are equally likely to show up, but Luke Skywalker is twice as likely to show up as Darth Vader.
The vehicles of Dark Times are much easier to figure out - there are actually not that many! Most of the maps are designed to be smaller, infantry-only maps, and so the "new" vehicles are far and few between.
