Please note that this is what i did - This is not a list of things that MUST be in a new race mod.
Its up to you what goes into your mod.
Ships - Probally the most important part of any new race. This can take up much of your modding time, although it helps to have images of the ships you want to use. In my case i used some sprites from an old pc game, the original ships but using a creating custom skins and a few “chop shop” ships. (see avatar)
Weapon Designs - i kinda cheated a bit here. I used the standard weapons and created varients. Although i added in a few new secret mega weapon
Modules - I did not really introduce many new modules into the game, so this part was quick and easy
Shield, Turret, Weapon Effects and Module graphics - This took the longest as there are tons of modules in this mod. Mainly due to some idiot making 3 varients of every weapon which required its own graphic.
here is a quick tutorial on what you need to do to make your own turrets -
Scenarios - Relativly quick, in this case i borrowed the original ones and used some of my new ships in them
Music - Find some music you would like to see as a battle theme.
Sound Effects - Some of the new weapons needed to sound different, so i found a few sound effects that seemed to match the weapon.
Please note that all this has taken me more that 4 months to do.
The only advice i can give is, In the end you should make the mod for yourself.
If your happy with it - post it, so we can enjoy it too.
