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

"Metal Factions" is a game for the spring engine with four original factions: AVEN, GEAR, CLAW and SPHERE.

2018/02/11 ------------------ NOTES v0.993 ----------------------

--- balance / mechanics

- increased AVEN "Defender" damage per second by 45% and increased cost by 20%

- changed AVEN and GEAR level 2 fighters to shoot a pair of faster missiles with slightly higher burst damage but less range
- increased HP of level 2 fighters (except SPHERE) by 100 (10-15%) and adjusted the costs
- slightly increased the projectile speed and reduced the range of fighter aircraft
- increased strafing fighter aircraft's acceleration
(these changes make strafing aircraft more cost-effective at fighting other aircraft in general, namely hovering aircraft which can shoot back efficiently)

- modified GEAR "Firestorm" to use incendiary rockets instead of fireball cannons

--- UI

- commands for building or upgrading metal extractors in an area now show up immediately when shift-queued

2018/01/31 ------------------ NOTES v0.992 ----------------------

--- new units

- added COMSAT station for all factions : a somewhat expensive building that can reveal an area of the map for 15s every three minutes
(these are an alternative investment to having to recurrently suicide swarms of air scouts to reveal areas behind enemy defenses)

--- balance / mechanics

- when a unit is ordered to attack a target and then ordered to move, it should keep attacking the previous target while in range

- improved the lua metal spot handler so that the metal decals are perfectly centered and more visible when resource highlight view is enabled

- removed global resource multipliers and other game options as some weren't processed properly
(they may be changed/restored at a later date)

- fixed a bug which prevented commanders from capturing enemy units, but sharply reduced the capture speed to 2/3 of the normal build speed
- "Builder Form" commanders have their capture speeds and terraform speeds set to 2x the normal amounts (same as their build speed)

- slightly increased the extraction radius of advanced metal extractors to ensure that no metal income is lost if they're built beside an existing basic extractors

--- UI

- updated the name and descriptions of metal extractors, now extraction rate multiplier and energy drain is shown on the tooltip

- added buttons that allow building the various metal extractor forms in an area : basic (level1), safe and hazardous (level2)
. these replaced the metal extractor area-upgrade and upgrade state buttons
. constructors will build the level2 forms beside existing level1 forms instead of reclaiming them first

- disable game speed indicator when the game starts to avoid overlapping clock/fps indicator
