Bionic Commando is a game that relies almost entirely on skill. The amount of time needed for a full 200 is reliant on how skilled you are at the game. You are going to need to master everything the game has to offer. Finishing Super Hard will push your skills to the limit, while A Real Challenge requires you to be a master of the Bionic Claw. There are light levels of collection involved, along with a few of those "I would never normally do this strange challenge unless there was an achievement for it" achievements. To say this game is challenging is an understatement. You are going to have to use a lot of effort to completely finish.
Step 1: Preparation
As you complete your first playthrough, be sure to use THIS THREAD to find every weapon/upgrade, THIS THREAD for all Yashichis locations, and THIS THREAD for intel locations (which are hard to miss except for a few rare cases.) All will be helpful for various achievements. You can go back to claim anything you skipped by replaying levels, but for the sake of speed it is best to find everything your first time through.
Step 2: Playthrough #1
For your first playthrough, choose the easy difficulty. Any difficulty unlocks Super Hard mode. H4><0rz can be unlocked on Super Hard, meaning a Hard playthrough is not required to obtain all 200.
Be sure to complete area 05 as soon as you can, as it grants you the rocket launcher, which is a necessity for a large variety of situations, and almost every boss. As for easily missed things, the Helmet, which is required for The Emperor's New Clothes, can be found in the secret tunnel between areas 15 and 18. This section of the game can be easily passed over. Make sure you enter every Safe Zone (friendly locations) and go in all of the red rooms to unlock every Challenge Room. You are going to have to give special kinds of effort for Clean as a Whistle, Cat Burglar, and Pacifist Pride. Be sure to read up on how to unlock them, and complete the requirements before you finish The Albatross.
Besides that, make sure to kill all non-required trucks during at least one Meet with Enemy sequence. If you haven't unlocked Faster Than a Speeding Bullet, you can unlock it quickly by standing in front of an enemy, letting him shoot you, using your arm to block his shots one burst at a time.
The last level is difficult on every difficulty (practically impossible on Super Hard,) especially on the outside swinging portion. If you are having any trouble with the last level, use THIS THREAD.
Step 3: A Real Challenge
Once you finish your first playthrough, it is time to attempt the game's gauntlet of 56 Challenge Rooms. These rooms range from easy to excruciatingly hard, without much room in-between. The difficulty curve is drastic, offering you a slew of easy levels to start, then bombarding you with challenges that can take upwards of 100 attempts to complete. The final room is above and beyond the most difficult. It is probably going to take over 100 attempts to complete, possibly over 300. THIS THREAD will give you a rundown on how to finish every challenge if you ever get stuck. Good luck.
Step 4: Playthrough #2
This is your H4><0rz and Elite Commando playthrough. Use THIS THREAD if you need help with Super Hard mode. It is filled with strategies and various bits of info to help you out. As a whole, you are going to need an insane amount of skill to survive Super Hard mode. Don't forget to access every hacking game along the way, and may god bless your poor, poor soul.
Conclusion:
What else can I say? The game is hard to complete. If you happened to miss anything, you can go back and replay any level you want. If you finish The Albatross and haven't unlocked a few select achievements, be sure you unlock them before you start your Super Hard playthrough. You should have unlocked all but H4><0rz and Elite Commando before you start Super Hard mode.
