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

************************** PATCH NOTES ****************************

2017/09/17 ------------------ NOTES v0.986 ----------------------

- fixed bug where GEAR's scout pad couldn't build air scouts (oops)

2017/09/17 ------------------ NOTES v0.985 ----------------------

- fixed bug that caused a crash when trying to start single player games through weblobby or directly through the spring engine binary
(didn't happen when using springlobby, though)

2017/09/17 ------------------ NOTES v0.984 ----------------------

--- new units

- added scout pads for all factions : cheap level 1 buildings that build air scouts
(this is to discourage some rushes and early blind rock-paper-scissors gameplay)

--- balance / mechanics

- significantly increased acceleration of SPHERE "Bit" robots
- fixed SPHERE "Golem" missiles being launcher horizontally
- increased damage per shot and reload time by about 20% for most missiles (damage per second is the same)

- reduced the cost of commander drones by 30%
- commander drones are now automatically destroyed if they somehow stray too far from the commander (twice as far as the retreat range, or about 1200)
- intelligence drones got even cheaper and drain 75 instead of 90 E/s but radar/sonar range was reduced from 1300/1100 to 1100/900
- light drones evened out across factions, weapon's base DPS was set to 50 (up from 35 and 44 DPS)
- medium drones changed: AVEN's a bit faster and deals more damage at shorter range, SPHERE's tougher but slower and got its weapon range slightly reduced

- reduced relative metal extraction multiplier for moho mines and exploiters from x3 to x2.5
- metal extractors and moho mines are now about 20% more expensive
- made metal extractors a bit tougher (from 300-500HP to 450-580HP)
- exploiters extract the same amount of metal as moho mines (was 93%) but increased energy drain from 80/s to 90/s
(this is meant to increase the payback times of rushing resource production, make exploiters more attractive and reward raiding more)
- removed energy income/cost from units that produce or drain less than 3 metal/s when moving

- units with build percentage greater than 50% explode normally and leave wreckage when destroyed
- prevent nano-frames from using self-destruct
- death explosions for most non-hazardous units and buildings deal L, M damage type instead of M, H
- AVEN "Zapper", "Penetrator" and "Excalibur" explode more violently when destroyed

--- UI / widgets

- updated upgrades' description to display their MINOR, COMMANDER or MAJOR type
- show message when construction orders for upgrades are denied because either own or type limit was reached
- removed white outline from the shield values on the tooltip

2017/09/11 ------------------ NOTES v0.983 ----------------------

--- balance / mechanics

- modified GEAR "Infernal Form" commander : now has two fireball launchers instead of a fireball/cannon combination and moves about 15% faster

- reduced range on GEAR "Destroyer Form" commander's energy bolt weapon by about 15%

- improved AVEN "Gamma Form" commander's weapon DPS by about 10%

- reduced CLAW "Slayer Form" commander's laser cutter energy consumption by 15%

- fixed error when drone upgrades where used with the latest AVEN and CLAW commander forms

- reduced speed and cost of most commander drones

- reduced slope tolerance for factories (this indirectly helps MFAI not to place them on slopes too steep for some of the units to exit)

- reduced speed and cost by about 10-20% and increased HP by about 15% for level 2 fighter aircraft

- increased acceleration and turnrate for AVEN "Runner" scout robot

- increased reload time and damage per shot by about 20% for most light and medium plasma cannons

- reduced cannon range and cost for GEAR "Might" and various level 2 Ships by about 10%

- increased GEAR "Kano" DPS by 10%

--- AI

- MFAI will now reclaim wreckages and other features much more effectively
- MFAI mobile unit evasion range reduced and uses half as many waypoints
- MFAI global awareness and tasks updates about every 6 seconds instead of 2
(these changes should boost performance on games against MFAI)

--- UI / widgets

- F10 key takes screenshot on png mode (F12 is for lower quality jpg)
- fixed issue with selection circles tilting to match the slope below the water line for ships near the shore

2017/08/28 ------------------ NOTES v0.982 ----------------------

--- balance / mechanics

- fixed an issue from the previous version where debris would drop after cancelling half-built aircraft (oops)

--- effects / visuals

- show effects when half-built units are destroyed or canceled

--- UI / widgets

- slightly lowered the minimum experience required for the COMMANDER award
- fixed the way the EFFICIENCY award is calculated (it was counting morphing, reclaimed units and upgrades as losses)

2017/08/17 ------------------ NOTES v0.981 ----------------------

- added CLAW "Slayer Form" commander : Greatly increased speed and firepower, but sharply reduced range.

--- balance / mechanics

- made aircraft drop wreckage parts when destroyed amounting to 40% of their metal value, same as other units (excludes commander drones)

- enabled an engine option to have weapons on turrets track targets a bit more effectively when either the unit or the target moves
- fixed an issue on some units with different weapons on the same turret/torso wrongly restoring position when only one is in range of target

- torpedoes from morphed CLAW commanders track their targets (same as all other morphed commanders)

--- effects / visuals

- improved CLAW Commanders' movement animation to scale with speed modifiers
- improved effects when features are fully reclaimed

--- UI / widgets

- show victory status as "undetermined" when the game is aborted instead of showing "defeat" for all players
- added support for MF data collection system
