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

2017/01/22 ------------------ NOTES v0.973 ----------------------

--- balance / mechanics

- increased SPHERE "Magnetar" HP from 10000 to 13000
- fixed an error that could happen when commanders with drone upgrades are destroyed while drone is under construction
- improved collision volume for GEAR "Barrager"
- fixed an issue where pop-up defense turrets would try to fire through terrain
- reduced weapon aim tolerance on SPHERE "Tycho" so it can no longer fire when moving away

--- effects / visuals

- improved SPHERE "Golem"'s wreckage

--- UI / widgets

- show an opaque grid covering the map surface outside of the playable area (widget by Pako)

--- AI

- MFAI avoids retreating mobile ground units that are lightly damaged if its team has a big enough mobile army compared to enemy mobile units + defenses
- MFAI won't build more than 3 energy storage and 2 metal storage buildings per player
- MFAI is less likely to build energy generators unless it's actually using the energy

2017/01/05 ------------------ NOTES v0.972 ----------------------

--- new units

- added GEAR "Beamer" : Pop-up Medium Laser Tower (level 1)

--- balance / mechanics

- improved GEAR "Infernal Form" commander's cannon damage/s by about 50% but slightly reduced area of effect and projectile speed
- improved GEAR "Dominator Form" commander's cannon damage/s by about 10%
- improved SPHERE "Gazer Form" commander's laser damage/s by 20%
- improved AVEN "Zeta Form" commander's damage/s by 10%, but reduced range by 10%
- improved weapons on "Builder Form" commanders sightly
- reduced CLAW "Assassin Form" commander's HP to 3000 from 3200
- adjusted damages and ranges of commander torpedoes in general

- SPHERE continuous beam weapons now get a bonus damage increase equivalent to the fire rate boost other weapons get with unit experience

- fixed collision volumes for several units (CLAW Bishop was the outlier with a volume much smaller than the actual unit)

- reduced flight times of vertically launched light missiles to avoid them flying in circles for too long after the target has been killed

- increased the price of aircraft by about 5-10%
- reduced speed of CLAW X, AVEN Falcon and AVEN Ace by about 8%
- increased CLAW Brute's cannon damage/s by about 20% and cost by about 5%

--- effects / visuals

- fixed CLAW wind generator's wreckage
- modified sound of CLAW energized plasma cannons (Nucleus and Mega)
- fixed movement animations on CLAW Knife and Centaur robots
- added specific icons for level 1 and 2 Plants and mobile builders

2016/12/25 ------------------ NOTES v0.971 ----------------------

--- new units

- added AVEN "Twister" : Light Gunship (level 1)
- added GEAR "Knocker" : Flying Cannon (level 1)
- added CLAW "Boomer (M)" : variant with M damage type rockets but higher DPS (level 1)
- added SPHERE "Tycho" : Ground Attack Aircraft (level 1)

- added GEAR "Barrel" : Amphibious Missile Robot (level 2)

--- balance / mechanics

- increased the total repair cost from 20% to 66% of the unit's energy cost
- units with lasers and cannons will shoot farther at targets above or below them (range sphere became an ellipsoid stretched vertically about 2x)
(this means lasers are more effective near cliffs and against air targets and high trajectory cannons can shoot farther uphill)
- slightly reduced how much extra range cannons get when shooting at targets below them (affects EMG on aircraft as well)
- fixed AVEN "Runner" not shooting at aircraft within range
- reduced GEAR "Firestorm"'s aiming tolerance but increased the turn rate
- made GEAR "Canister" more able to shoot at targets on top of tall terrain formations or behind them
- SPHERE "Magnetar" blasts no longer generate craters
- CLAW "Grinder Form" commander can no longer be carried by level 1 air transports
- removed passive HP regeneration from units with less than 90% build completion

--- effects / visuals

- fixed an issue that could make ground units move along the ground without displaying their "walking" animation
- fixed some effects being visible to enemies across the map when they shouldn't
(namely commander morph particles, Magnetar and Zephyr effects)
- updated the sounds of several energized plasma cannons, namely AVEN commanders'
- improved wreckages for SPHERE "Trike" and "Quad" and GEAR "Marauder"
- show effects when units hit the ground or water surface after falling from destroyed transport aircraft
- slightly improved some water explosions
- SPHERE "Magnetar" glows brighter as its weapon charges

--- UI / widgets

- added "MENU" button on the top right corner
(same as shift-esc key combination)

--- other

- renamed GEAR "Voodoo" to "Zipper"
