[TAS] Pleiads Arcade [Tehkan] 10 loops (99,520)
45Tool-assisted superplay (TAS) of Pleiads Arcade 10 loops (99,520)
---Each loop consists of 4 waves
---Wave 1:
-Defend the Earth against attacks from space
-You have to shoot 16 aliens.
---Wave 2:
-You are leaving Earth to go into space
-The aliens start small and a hit anywhere destroys them. You get 50 points for this.
-Once they get big, only a hit in the middle will destroy them.
-If you shoot them to one side, a flame appears and you get 20 points
-You can constantly shoot them on one side to get 20 points each time. You can rack up many points like this.
-But be careful, when you hit them, they stop moving sideways and fall directly on you.
-When you shoot one in the middle you get 100-400 points
-100 if there is no fire
-200 with a burning wing
-400 with two burning wings
-If you wait too long, the fire eventually goes out
---Wave 3:
-Destroy the alien Mothership.
-For this wave, the game allows you to shoot 2 bullets at once instead of 1 elsewhere in the game (Tehkan version)
-Your goal on this wave is to put out the five exhaust flames under the Mothership. You can only extinguish a flame when a chamber door is open.
-Each time you fire a flame, Mothership's bonus increases.
-You get the bonus at the end of the wave
-The wave ends if you shoot all 5 flames on the mothership or shoot 16 aliens, whichever comes first.
-Shooting the mothership does nothing and doesn't give you any points.
-The bonus starts at 100 for the first flame of the first loop and doubles for the other flames.
-So for loop 1 the bonus is: 100,200,400,800,1600
-For each subsequent loop, the bonus starts with 100 more points.
Loop 2 = 200 400 800 1600 3200
Loop 3 = 300 600 1200 2400 4800
Loop 4 = 400 800 1600 3200 6400
Loop 5 = 500 1000 2000 4000 8000
Loop 6 = 600 1200 2400 4800 9600
-But a problem arises for loops 7 and 8 because the number displayed cannot be greater than 9999 points
Loop 7 = 700 1400 2800 5600 11200 but the game displays 1200
Loop 8 = 800 1600 3200 6400 12800 but the game displays 2800
-After that the bonus restarts at 100
Loop 9 = 100 200 400 800 1600
Loop 10 = 200 400 800 1600 3200
------But there is a much bigger problem than that!!!!!!!! -------
-On the Tehkan and Centuri version (I didn't test the other clones), when the 5th digit is displayed, the game gives the 4th instead.
-I think it's because the bonus is added to the score 1 frame before the bonus is incremented. You can clearly see this if you watch the video frame by frame.
-At 1:36 I fired the Mothership for the 5th time in loop 1 but the score went from 1670 to 2470 giving me 800 points instead of the 1600 displayed.
-At 11:42 I fired the Mothership for the 5th time in loop 6 but the score went from 43020 to 47820 giving me 4800 points instead of the 9600 displayed.
-And because of this bug, loops 7 and 8 are no problem because the game gives you 5600 and 6400 points respectively.
---Wave 4:
-You have just received an SOS that the earth is under attack. You must navigate around the parked fighters and land on the target to return to wave 1 and start the battle again.
-The target is divided into 5 zones: 4 2 1 3 5
Zone 1: The exact center pixel and 1 pixel on each side gives you the maximum points (3 pixels wide)
Zones 2 and 3: one pixel on each side of zone 1 gives you the middle amount of points
Zones 4 and 5: all other positions earn you the least points
-Scoring starts with 500 points for zones 4 and 5, 1000 points for zones 2 and 3 and 1500 points for Zone 1
-Each subsequent loop increases the bonus points by 500 and stops at 4000 like this:
Loop 1 = 500, 1000, 1500
Loop 2 = 1000, 1500, 2000
Loop 3 = 1500, 2000, 2500
Loop 4 = 2000, 2500, 3000
Loop 5 = 2500, 3000, 3500
Loop 6 = 3000, 3500, 4000
Loop 7 = 3500, 4000, 4000
Loop X = 4000, 4000, 4000 probably resetting at loop 256 (to be determined)
-And you get fireworks for every 500 points
To find the high score of this game on Twin Galaxie, you must search Pleiades and not Pleiads.
The highest score on Twin Galaxies of 4,000,000 (13 hours) is achieved on the Centuri version of the game.
I think there should be 2 different entries, one for Tehkan and another for Centuri because of the differences between the two.
In the Centuri version, the player moves twice as fast as the Tehkan version and can have 2 bullets on the screen at once everywhere instead of just on the Mothership wave.
I think the Centuri version of this game is too easy. I wish I had this version in my arcade, my high score would have been much higher :)
I put a side by side comparison of the two versions to show the difference at the end of my video. (21:22)
