This guide is for Mushihime-sama Futari ver 1.5. I previously wrote a short explanatory guide for ver 1.0, but that version is rather obsolete these days, with ver 1.5 being the only one people play seriously now.
There are two characters, Reco and Palm. In addition there are two types of each to choose from. These are termed “Normal” and “Abnormal”. All four character-types play quite differently from one another. In the section below, note that I’ve rated Speed (S), Range (R), and Power (P) for each shot type (A and C) for each character-type, from 1-10 (10 is the best). These are based upon my own estimation after extensive use with each character type.
___Normal: Her A shot [S:3 R:4 P:8] is similar to S-power from the prequel, while her C shot [S:6 R:10 P:6] is similar to W-power from the prequel. Perhaps the most well-rounded character-type in the game.
___Abnormal: Her A shot [S:10 R:4 P:9] moves faster than her C shot, and is similar to S-power from the prequel. In addition, the child pods attach to whatever enemy is near them when the A button is held down. Her C-shot [S:6 R:9 P:6] is similar to a shot-type seen in Ketsui. Overall the hardest character to handle in the game, though when fully powered her A shot is stronger than anything Normal Reco can muster. She is also faster than the Normal-type. She requires a great deal of skill, but in the right hands she can do serious damage.
___Normal: His A shot [S:4 R:9 P:7] is a DDP-esque laser, moderately powerful but quite effective. His C-shot [S:8 R:7 P:6] is similar to M-power from the prequel, and is strong and fast with a decent range once powered up.
___Abnormal: His A shot [S:2 R:9 P:10] is the strongest shot in the game, beating out Abnormal Reco’s A shot. It also has a great range. His C shot [S:9 R:3 P:5], while it looks very cool, is actually the weakest in the game. It has the worst range as well.
Like the first game, tapping C very fast allows your lasers to stop firing, so you can do damage solely with your shot. This works best with Normal Reco. This is useful in many instances in Maniac mode, particularly when needing a quick burst to the red zone of the chaining bar on a boss when there is very little life left before its next phase change (or its complete destruction).
IMPORTANT: Anytime you are not pressing A, you suck in all the gems on the screen within a certain range. Any time you press A you suck in all the gems on the ground.
There are three modes in the game: Original, Maniac, and Ultra.
[3.1] ORIGINAL MODE
Original mode is characterized by fast but less dense bullet patterns.
Scoring is based on two multipliers: the overall counter and the stage counter. It is unclear how they are combined together, though it is clear that both influence the scoring.
[188.8.131.52]THE OVERALL COUNTER:
This is the bigger of the two counters in the upper left of the screen. It increases from the start of the game until the end of the game with no reachable maximum. The overall counter changes color from green to blue. It is green when the 100 digit is from 0-4, and it is blue when the 100 digit is from 5-9. Each time you die, your counter decreases by 1/3 (e.g. if you have 900 gems, after 1 death you will have 600). When you bomb this counter also decreases over the duration of the bomb (on average 10-15%??).
[184.108.40.206]THE STAGE COUNTER:
This resets at the start of each stage, and maxes out at 9999. The stage counter appears under the overall counter in the upper left of the screen. Each time you die, your counter decreases by 1/3 (e.g. if you have 900 gems, after 1 death you will have 600). When you bomb this counter also decreases over the duration of the bomb (on average 10-15%??).
In order to get large gold gems, you must kill enemies with the C button when the overall counter is GREEN, and the A button when it is BLUE.
Here are the values of the different gold gems (in other words, how much each adds to your counters when you get one):
Gems in the sky:
Large green-aura: +4
Small green-aura: +2
Gems on the ground:
Large green-aura: +20 (<--MOST VALUABLE)
Small green-aura: +10
[220.127.116.11] GREEN-AURA GEMS
These are the secret to scoring in Original mode. The closer you are to enemies when they die, the more GREEN-AURA gems you can absorb. In order to trigger them you must kill the enemy with the appropriate shot, based upon the status of the multiplier (see sections 18.104.22.168 and 3.1.2 for details). These are twice the value of regular gold gems, and they only appear for a second or two once an enemy dies, whereupon they revert back to yellow. So, you must be quick, and close to enemies when they die whenever possible (and either let off the A shot or hold C to absorb all the gems quickly).
Bullets gradually increase in speed, in effect increasing the game's rank, as the overall counter increases. When you reach 70,000 on the overall counter, you max out the rank in the game.
Maniac mode is characterized by dense bullet patterns at moderate speeds, as well as the most complex scoring of any of the game modes.
Scoring is based on one multiplier, which is termed the overall counter. This counter is only triggered by killing enemies with the A shot when the chaining bar is at zero. Each gem absorbed at this time has a blue-aura, and the value of the multiplier is added to the value of each of these gems, which increases your score once you absorb them.
[22.214.171.124]THE OVERALL COUNTER:
This is the counter in the upper left of the screen. It serves as a multiplier added to the value of the blue gems you obtain. It maxes out at 9999 and is reset to 0 at the start of each level. Gold and green-aura gems increase this counter, while blue-aura gems decrease it. Each time you die, your counter decreases by 1/3 (e.g. if you have 900 gems, after 1 death you will have 600). When you bomb this counter also decreases over the duration of the bomb (on average 10-15%??).
[126.96.36.199]THE CHAINING BAR:
This appears under the overall counter and increases from blue to red. As long as you chain enemies with the C shot, it will increase. In addition, it increases to red as long as you hold your C shot on a large enemy (like a boss). This bar decreases rapidly to zero as you hold the A shot. Kill an enemy with the A shot when the chaining bar is red and you’ll get double the gems. Kill an enemy with the A shot when this bar is empty and you’ll spawn blue-aura gems (see below). Basically, the scoring system and gameplay flow are based upon using the C shot when the chaining bar is between zero and MAX, and using A when it is at either zero or MAX.
Whenever you kill an enemy, all the bullets on the screen from that enemy are changed into gems, and in addition some gems are spawned from the enemy itself. In order to get large gold gems, you must kill enemies with the C button when the chaining bar is red (any time the chaining bar isn't red you will get small gems). Kill them with the A shot when the bar is red and you get double (or more??) the large gems, which can quite literally fill the entire screen with gems!
Small gem: 5pts
Large gem: 10pts
Small blue-aura gem: 5 x multiplier
Large blue-aura gem: 10 x multiplier
Values added or subtracted from the Overall Counter (i.e your multiplier):
Small gem: +2
Large gem: +5
Small gem (on ground): +10
Large gem (on ground): +20
Small Blue-aura gem: -15
Large Blue-aura gem: -30
To trigger these in Maniac mode, you need to kill enemies when the chaining counter is red and not be holding the A shot when you absorb them. These are worth double the normal gems (large and small), so it’s well worth it to learn how to trigger these if you want to score well. They only glow green for a second or two before they revert back to yellow, so you must be quick and suck them in by letting off the A button. The best way to get a ton of gems quickly is to wait for an enemy to fill the screen with bullets, then kill it with the A shot when the chaining bar is red, then quickly switch to the C shot (or just don’t hold any button down) to have the nearby gems turn green as you absorb them.
To trigger these you must destroy an enemy with the A shot when the chaining bar is empty (no color showing). Every blue-aura gem is worth the value of the overall counter x5 for small gems and x10 for large gems at the time it is absorbed. Once absorbed, they are subtracted from the overall counter. Since the max multiplier is 9999, the max point value you can get from a single large blue-aura gem is 99,990pts.
[3.3] ULTRA MODE
Ultra mode's scoring is the same as Original mode with the following changes:
-Counter changes from green to blue every 2000
-Stage counter does not max at 9999, but rather continues indefinitely
-Bullets never change speed as your overall counter increases
*There is no rank in Maniac or Ultra mode*
