1. This is a little more complicated.  First, you'll need to download a program that allows you to fly the TIE Defender in XvT but also adds the M/FRG and others.  It can be found at http://members.home.net/draxon/SP3-50B4.zip and you might already have downloaded it for XvT Free #6. Download the file SP3-50B3.ZIP, and follow the instructions CAREFULLY.  Be sure to back up any files you think you may need to.  Run the program, and be sure to turn it on. You'll know you've hot it on when your cursor in XvT has become am ISD. You will not be able to ply this battle without it and you cannot reverse the installation order.
2. Copy the is2cb1w1.tie, is2cb1w2.tie, is2cb2w1.tie, is2cb2w2.tie, is2cb3w1.tie, is2cb4w1.tie, is2cb5w1.tie, is2cb6w1.tie and is2cb6w2.tie files and the Combat Imperial.lst, Mission.lst and Rebel.lst files of this custom mission into your "Combat" folder.
3. Copy the is2sb1w1.tie, is2sb1w2.tie, is2sb2w1.tie, is2sb2w2.tie, is2sb3w1.tie, is2sb4w1.tie, is2sb5w1.tie, is2sb6w1.tie and is2sb6w2.tie files and the Train Imperial.lst and Mission.lst files of this custom mission into your "Train" folder.
4. Copy the Battle Battle3.lst and Mission.lst files of this custom mission into your "Battle" folder.
5. Copy the is2sb1w1.lst, is2sb1w2.lst, is2sb2w1.lst, is2sb2w2.lst, is2sb3w1.lst, is2sb4w1.lst, is2sb5w1.lst, is2sb6w1.lst, is2sb6w2.lst, is2cb1w1.lst, is2cb1w2.lst, is2cb2w1.lst, is2cb2w2.lst, is2cb3w1.lst, is2cb4w1.lst, is2cb5w1.lst, is2cb6w1.lst and is2cb6w2.lst files and the IS2B1, IS2B2, IS2B3, IS2B4, IS2B5 and IS2B6 folders of this custom mission into your "Wave" folder. (place the directory as a subfolder from /wave... as /wave/IS2B1 etc.)
6. Create a new pilot for the mission based on your name or PIN and the mission number. For example, SL Stele playing Free Mission 80 would make a new pilot file named "StelFM80." or a Pilot with PIN 2883 playing Free Mission 69 would make a new pilot file named "2883fm69"
7. Begin flying Battle One, play on till you've flown the 3rd mission of Battle Three.

• IMPORTANT! ONLY USE THE SINGLE PLAYER MISSIONS (TRAINING MISSIONS) FOR HIGH SCORE SUBMISSION.
• For these missions to work in MP, all players must have them installed on the same mission numbers, in this case "110" to "119". Preferably do not change these numbers.
• TAC won't let you fly Combat Missions or XWA Skirmishes for FCHG Points, use the Single player mission for all TC flying outside of combat competitions.

The battle is a conversion of the original XWA skirmish files used (as far as available) using a "XvT Skirmish" template to test this mission type's usefulness in war gaming situations with the ultimate goal to come to war games on more platforms then just XWA. This offers some limitations towards this battle as a Single-Player experience:

• The goal in a Skirmish is to destroy all opposing forces - as such all the missions have a Primary Goal of destroying 100% of the opposition.
• War gaming Skirmishes hold almost 200 craft (2x94) - which means that some of the larger scale battles make for very long missions with quite a lot of waves (XvT can hold 32 craft at the same time, this means that you'd have up to 6 waves - per craft)
• War gaming Skirmishes hold also a maximum of almost 200 craft - this means larger battles are split up in waves. To keep in with the full conversion these waves have not been combined to single missions - which means that you will probably have a larger mission in the first wave then in the last. (When both forces have been depleted)
• Because the story line is based on actual tactics and strategies it doesn't hold to the classical battle structure of going towards a climactic final battle and you won't always have the opposition you'd wish you have - this is more realistic but it might cause strange effects for the classic mission flier. See it as "story driven"
• Some of the XWA craft and possibilities are not there in XvT - adjustments have been made and this is the reason behind the required shippatch use.
• Skirmishes have no briefings to speak of, the "animated" briefing still reflects this, Officer Questions, Radio Messages and such have been added.
• The single player is always on the side of the winning team - or it could be next to impossible to complete. This is why the battle has been cut into 3 pieces of 3 missions each in which you fly for each of the 3 teams of IS2:DH. This means that the player doesn't follow the events of the wargame in complete chronological order (going through battle 1,3,2,4,5,6 in that order).
