I'm currently working on a new mod, my Last one died with Blackout 2003
My current one i began with a combination of TDM and the Ultimate Stratigy Mod, and have created a new system movement /combat movement system.
As well as increased sizes of the first few ships ie Es1 Es2 Es3... To keep smaller ships in play. I've given the smaller ship sizes a combat movement bonus: ES+3 FG+2 DD+2 CL+1 Smallftr+2 Medftr+2 HvyFtr+1...
So smaller ship are faster in combat but the same speed on the map (so the chug along with the fleet but got to full steam on the attack.) However, there is still alot of work to do, as im also adding weapons and components as well as revamping Sensor and Cloaks. Now only the hardest to get sensor detect all cloaks, all others are sensor specific. Passive sensors see passive cloak etc.
