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.

REQUIRES SPRING VERSION "104.0.1-1429-g1add37c maintenance" or later

2020/01/23 ------------------ NOTES v1.27 ----------------------

--- Balance / Mechanics

- slightly increased cost of units that have relatively short range weapons with relatively low projectile velocity
(they're likely to shoot over each other and still hit their targets)
- slightly decreased the cost of units with relatively short range lasers (< 450)
- slightly reduced the cost of units with relatively high durability/cost
- slightly increased the cost of units with relatively high speed
- slightly reduced the discount units get from having energy-intensive weapons

- slightly increased the cost penalty for relatively high HP air units (including flying spheres, which are about 5% more expensive)
- slightly decreased cost on units with weapons which have significant aiming angle restrictions
(mostly aircraft, this compensates the previous cost increases and even makes many of them slightly cheaper)

- increased AVEN "Warrior" HP from 1380 to 1480 and adjusted cost
- increased AVEN "Bold" HP from 1350 to 1450 and speed from 1.9 to 2.0 and adjusted cost
- increased AVEN "Kit" rockets' speed by 33% and adjusted cost

- increased GEAR "Box" HP from 1500 to 1650 and adjusted cost (still cheaper than previous version despite the HP increase)
- increased GEAR "Canister" range from 640 to 660 and adjusted cost
- increased GEAR "Barrel" range from 650 to 720, reduced speed from 1.4 to 1.2 and adjusted cost
- increased GEAR "Instigator" speed from 2.05 to 2.15 and adjusted cost

- increased CLAW "Boomer"'s rockets' speed by about 15% and adjusted cost
- increased CLAW "Boar"'s movement and projectile speed by about 10% and adjusted cost (it's significantly more expensive now)

- increased SPHERE "Crustle" movement speed from 1.9 to 2.0 and adjusted cost
- increased SPHERE "Stout" dmg/s by about 10% and adjusted cost
- SPHERE "Hanz", "Charger" and "Golem" require a bit more energy to fire their weapons

- reduced start velocity and increased turn rate for AVEN and GEAR fighter aircraft's missiles
(to avoid them overshooting their targets)

- increased AVEN, GEAR and SPHERE level1 bomber aicraft bombs' damage by 10% and adjusted cost

- energy storage buildings are now about 20% cheaper

- reduced the threshold for relatively heavy units to be push-resistant

- adjusted commanders weapons to improve consistency on the relative strength of surface weapons and the water weapon
. CLAW "Slayer" form gets about 20% increase in laser cutter dmg/s but torpedo reload time increased from 3 to 3.5s
(the laser cutter visual effects are also more intense)
. GEAR "Devastator" form gets about 5-10% damage nerf on the energy bolt and laser
. CLAW "Grinder" form gets 10% less range on the torpedo
. AVEN "Omega" form gets about 10% more dps on torpedos and double energy cost on the disruptor

- removed ON/OFF button from SPHERE "Tick"

- increased cost by 25% of "cheap" AVEN, GEAR and CLAW mobile radar jammers that can become fully invisible when cloaked
- increased the energy costs per second to maintain cloak from 30-75 to 50-105
(also added a hint about their invisibility potential on the unit tooltip)

2020/01/12 ------------------ NOTES v1.26 ----------------------

--- Balance / Mechanics

- reduced range of SPHERE "Gaunt" from 680 to 670
- increased the range of level1 missile units to 680
(this is to ensure they outrange Gaunts and counter them properly due to the damage types)

- fixed issue with collision volumes for fortification gates after they open/close

- SPHERE "Gaunt"'s body no longer instantly "snaps" to walking pose after aiming while moving

2020/01/10 ------------------ NOTES v1.25 ----------------------

--- New units

- added SPHERE "Double" : level1 Raider Vehicle

- added CLAW "Ringo" : level1 Raider/Skirmisher Robot equipped with an energy ring launcher

--- Balance / Mechanics

- increased GEAR "Kano" range and cost by about 15%
- GEAR light plant can now build "Igniter" incendiary raider vehicles
- renamed GEAR "Raider" to "Assaulter" and increased its speed by about 6% and cost by about 3%

- increased CLAW "Knife" HP by 16% and cost by 8%

- SPHERE "Gaunt" : increased damage per shot and reload time but decreased dmg/s by about 10%, speed reduced by 16%, cost reduced by about 10%
- SPHERE light plant can now build "Gaunt"

- further general cost change of up to about -5% to +5% penalizing relatively strong or long-ranged units (mostly level2)
(short ranged level1 units should be relatively cheaper now compared to the other options - this is applied on top of the previous cost changes)

--- Sounds

- modified sounds for some of AVEN and SPHERE light vehicles
- modified sounds of some large explosions to differentiate them from long range plasma cannon explosions

--- AI / MFAI

- modified AI to use the new build options
- AI Light factories will sometimes build a set of half a dozen raiders and then restore the normal queue
