Far into the future, different factions fight throughout the galaxy for control of resources using armies of advanced machines...

"Metal Factions" is TA-inspired game that runs on the Spring RTS engine and has four original factions: AVEN, GEAR, CLAW and SPHERE.

2018/11/30 ------------------ NOTES v1.03 ----------------------

--- balance / mechanics

- reduced the dmg/s of CLAW "Slayer form" commander's torpedo by about 20%

--- AI

- easy and normal AI should grow a bit slower but be harder to rush and use the commander better when base is under attack

--- UI

- fixed an error that could appear sometimes when right-click-dragging to draw line formation

2018/11/26 ------------------ NOTES v1.02 ----------------------

--- balance / mechanics

- SPHERE "Chroma" and "Comet" flying spheres explode more violently when killed
- AVEN "Bolter" now shoots in 6 round bursts instead of 2 round bursts, but reload time is tripled and cost increased by 7%
- fixed "rare" issue where long range missiles could become untargetable and explode both on the platform and on the target

--- AI

- make AI less likely to get stuck without making level1 and level2 factories

2018/11/22 ------------------ NOTES v1.01 ----------------------

--- new units

- added AVEN "Perceptor" : Intelligence hovercraft. Provides radar, sonar and radar jammer

--- balance / mechanics

- Fixed GEAR energy storage not being able to be built underwater
- increased the terrain slope tolerance and reduced the death blast damage of AVEN "Runner" to match the other small robots
- AVEN "Knight" has move state set to "hold position" by default
- increased the movement footprint for a many small and medium robots so they'll clump together less when moving in groups
- removed the 2x vertical range bonus on short range flamethrowers (GEAR) and laser cutter weapons (CLAW)
- CLAW "Slayer" form commander gets 10% increased speed and 10% reduced range
- CLAW "Sword" : reduced laser cutter range by 10%
(this means flamethrower and laser cutter units can no longer hit air in most situations)

--- AI

- more likely to build energy generators in general to try to achieve a higher energy surplus
- more likely to build wind generators
- fixed AI not building geothermal generators
- fixed issue with MFAI assigning too many builders to dedicated roles and not leaving any to build level2 factories back in base
- fixed AI skipping level2 factories unless it had significant surplus energy and full stores
- AI builds radar and radar jammer units from the advanced factories earlier and is more likely to rebuild them if they're destroyed
- more likely to build artillery units against enemies who make lots of static defenses
- AI builders tasked with building metal extractors now build defenses and radars nearby instead of spending time moving around
- fixed check for idle builders to avoid them getting stuck
- less likely to move relatively fast units from the main party to the raiding party if unable to attack (requires much longer periods where it's unable to do so)
- normal MFAI is slightly more conservative when attacking (will try to grow its numbers further before doing so)

--- UI/visuals

- change dust particles from small and medium explosions to be more noticeable while keeping them finer for large explosions
- modified the chat widget to avoid breaking words when splitting text to lines
- modified AVEN Bolter's model to make it look less blocky and reflect its light armored status
