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.

2018/10/18 ------------------ NOTES v1.000 ----------------------

--- new units

- added long range rocket platforms for all factions (level 2), which can hold up to 4 rockets each
- the rockets have relatively low HP and L armor type and can be shot down by enemy weapons which target fast units and aircraft effectively and have good range
- the rockets' range covers the whole map

New rocket types:
- Nuclear Missile: expensive missile that will likely kill all units on a large radius unless it's shot down while still far from target
- Destruction/Construction "DC" Missile: can kill small clusters of units, provides temporary vision and spawns a construction tower on impact

(these are identical for all factions : faction-specific ones may be added at a later date)

--- balance / mechanics

- fortification walls have H armor instead of M

- comsat stations reveal the targeted area for 30s instead of 15s
- fixed issue with comsat beacons being targetable and blocking projectiles

- made relatively slow units and defenses and units with relatively high HP/cost up to 10% cheaper
- made relatively fast units or units with relatively powerful and long-ranged weapons up to 10% more expensive

- reduced the death explosion damage and area of effect for most level 1 ground units

- removed experience gain by dealing the killing blow to enemy units
(this means that having the HP bar drained by enemy fire is now worth 50% as much experience as killing an enemy of equal value instead of 25%)

- removed obscure flanking mechanic unless specifically stated
(units took up to twice as much damage when being hit from different directions)

- increased the HP and speed of level 1 light tanks by about 10% and adjusted the cost

- GEAR "Canister" and "Eruptor" are set to hold position by default
- GEAR "Infernal" form commander got about 5% less direct weapon damage on the fireball cannon and 5% increased range on the torpedo weapon
- replaced GEAR "Crock" with "Rhino" : Amphibious assault gun with 33% front-back dmg resistance bonus/penalty a forward-only cannon and a secondary laser turret
- CLAW "Assassin" form commander got about 5% less range, reduced HP by 100 and 25% higher reload time on its torpedo weapon
- CLAW "Longhorn" : increase model height to compensate for its flatter trajectory
- SPHERE "Emerald" form commander got 5% more movement speed but 9% reduced range and reduced energy cost to fire from 160 to 120 E/s
- SPHERE "Nova" form commander got 10% increased range
- SPHERE "Ruby" form commander got 15% reduced energy cost to fire
- increased the HP of SPHERE "Rock" and "Slicer" by about 10% and adjusted the cost

- increase damage and reload time for light missiles by about 20-40%
- make large fast missiles L damage instead of M and reduce the area of effect (from 80-120 to 60)
- reduced range by 200 on static launchers, increased turret turn rates and reduced pop-up delay and reduced the unit costs significantly
(this increases the effectiveness against light units and aircraft, including long range rockets, relative to against medium/heavy armored units)
- missiles have cylinder targeting with 2x range altitude limit and fly a bit faster
(so they're also better at shooting down long range rockets)
- CLAW "Hyper" is a bit taller when open and also slightly improved the model

- changed minor regen upgrade to give 1 + 0.1%HP per second instead of 2 HP/s
- increased flat regen on major regen upgrade from +2 to +3 HP/s

--- UI / Visuals

- Made lasers thicker to make them shinier
- SPHERE "Opal" beams and forms have been renamed to "Emerald"
- big explosions shake the camera
- used a rounder model (more faces) for SPHERE "Chroma" and "Magnetar"
- moving mouse to the upper part of the screen will show a less intrusive "press space to view chat" hint instead of showing the chat
- GEAR "Heater" tank has a longer and narrower body to differentiate it more from the "squarer" slower tanks

--- AI
- SPHERE AI will make more long range missile towers instead of static sphere towers
- AI moves attacking groups more decisively when targeting undefended clusters of enemies
- fixed AI definition of number of builders by task type
