-changing the trap mechanic: there is no longer melee trap, since they are super unpredictable, so I changed them into pulsar trap and shield laser platform for offensive and defensive purpose.
-changing PD missile into Multi-purpose missile, the behaviors changed into lower launch frequency and a lower thrust, the damage per missile increased to 40 from 5, now has 1 missile per second from 10 / sec. The thrust is 1000 (from a big number) but have a much higher initial boost (x20) and a boost time of 1.5 s. Launch power also changed to 60 per shot.
-add new weapon Lighthouse laser

-further decreasing the AOE of the main laser gun to 100 units (from 200). It's min charge time also change to 3.5 s from 3.75 s
-decreasing the shield s2 to 1150 (from 1500) as same as recharge rate
-reducing the lifetime of ancient torpedo to 20 s (from 30 s)
-immobilizer will launch in slower rate from 1 per sec to 0.2 per sec. The mass of the immobilizer increased so it should be more effective individually
-add small cannon for smaller scale ship

-increasing main laser gun max charge time to 5 s, min charge time to 3.8 s (from 3 s and 1.5 s)

-making healing drone launch frequency lower, from 0.5s delay to 4s delay, and the individual's healing power stronger, from 100 to 1000
-adding a new weapon Rapid Accelerator.
-also lowering the main laser gun AOE from 300 to 200, since AOE will provide to much efficiency

-Making regular healing beam cheaper to 90 p from 300 p, and increasing it's range to 1500, increasing it's power to 370 healing power

Revisit the game, make some change to the files to have some fun.
-Rebalancing shield broker -reducing the range from 3000 to 2000, damage from 250 to 200, add a dispersion about 8 deg.
-Reducing shield s2 health from 2500 to 1500, so it will only be able to take one nuke, but the recharge speed should -still be handy.
-Main laser gun now has 8500 energy cost/shot instead of 5000
-Particle accelerator now will have 3200 damage, and a splash radius about 10 unit instead of 1500 damage and 1500 splash radius with 7000 energy cost. However, the cannon booster, now called cannon convertor will increase the splash radius by 45% and 125 unit each time while reduce the damage half at the same time. It will also now have an increasing energy cost effect to the cannon it attached to, by 15% and +10 base value each time.
-Spread arrow will now have 120 energy cost/bullet instead of 50.
-Ancient torpedo now have 2950 p instead of 1000.
-Add weapon ancient rail-gun.
-Add healing drone..

-Basically lowering the radius of "Shield S2" from 1000 to 300.
-Tweaking the mass of small and medium armor, making them a little bit lighter (density set to 0.1), to make them better for teleporting.
-Decreasing the health of the large armor, durability reduced from 4 to 3.

-Adding weapon "Spread Arrow".
-Reducing the AOE effect of "Main Laser Gun" from 500 to 300.
-Reducing the firing arc of "Shield Broker" from 177 degree to 115 degree.

-Adding NOCLIP_ALLY feature to drones and the modules created by launchers

-Tweaking the explosive radius of "PD Missile"

-Removing generator feature of "Shield S1" and "Shield S2", and lower their P values. At the same time, increasing the hitpoints of those shields.

The reason of this change is that some types of damage could apply to shield directly without a direct hit, and this could causes an inter-explosion of the ships, which use those shield.
