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.

2019/03/09 ------------------ NOTES v1.061 ----------------------

- fixed SPHERE "shine" wreck error (typo on the previous version)

- modified AVEN "Ghost" bombs' trajectory to avoid it missing nearby targets

2019/03/05 ------------------ NOTES v1.06 ----------------------

--- New units

- split the existing AVEN "Ace" into two energy-intensive aircraft:
. AVEN "Ghost" : Stealth Bomber (can cloak and has radar jammer)
. AVEN "Ace" : Very Fast Assassination Bomber

--- Balance / Mechanics

- increased reload times on AVEN, GEAR and SPHERE armed scouts (~20% dmg/s dps reduction) but kept costs similar

- increased speed of commander "Builder" and some of the average-moving commander forms by about 10%

- fixed SPHERE sphere factory's wreckage not blocking units
- fixed AVEN sentinel aiming from wrong barrel

- reduced energy efficiency for AVEN energy bolt weapons, slightly increased damage per shot and reload time (dmg/s is about the same)

- merged floating versions of basic turrets with the land versions to clean up the build menus
- radar jamming tower can now be built on water
- GEAR's basic pop-up turrets now also pop-up when built on water
- long range missile platforms now float on water
- increased torpedo flight times to avoid them falling short of targets
- GEAR Noser : made torpedoes properly track their targets
- increased turn rates on construction ships
- reduced the minimum water depth for medium and large ships from 25, 50 to 18, 30
- slightly reduced the targeting radius of submarines to avoid them being targeted by anti-surface weapons

- incendiary explosions that happen in the air trigger a mid-air fireball with 2s duration instead of the normal 20s on the ground
- GEAR "Destroyer" form commander was renamed to "Raider" and modified to have a dual flamethrower and vertically launched incendiary missile system
- GEAR "Infernal" form commander can now explode its fireballs mid-air
(this makes it a potentially dangerous against low gunship swarms, like the SPHERE "Nova" form)
- rebalanced fire AOE weapons : relatively fast-firing ones (Infernal form and Firestorm) got fire rate penalties and increased cost while slower firing ones got 5-10% cheaper

- CLAW "Dizzy" : reduced range by 10%, increased speed by 15% and fire rate by 60% and increased cost by 35%
(to make it crazier and differentiate it more from the other spinbots)

- fixed a potential scouting exploit with the area-metal-extractor commands

- fixed range upgrades not updating the dynamic damage drop with distance

- modified how aiming is done on some robots with different weapons on each arm to prevent conflicts

--- Sounds / Animations

- GEAR "Harasser" now properly turns it's barrel sleeve vertically when aiming
(note that this didn't prevent it from firing)

- modified the sounds for light plasma cannons and small incendiary explosions

- removed annoying looping sound when mobile radar jammers and intelligence drones are guarding other mobile units

--- UI

- enabled outline widget by default to make units easier to see
- made build and attack range indicator lines more visible
- show extra range circles for secondary weapons (red or purple for torpedoes)
- tooltip shows if buildings can be built on land and/or water

- disable wind or tidal generators on the build menus if the map has low average wind or tidal strength

- added hit-n-run mode option for attack aircraft : when attacking they automatically retreat in the opposite direction after firing
(hopefully this will make strafing aircraft more useful, it's going to be enabled by default only on bombers with a long reload time)

- added ON/OFF button to radar/sonar ships

- 10s after the game ends, a 30s countdown timer starts and when it ends the game exits automatically
