Use it to jump straight to the chapter where you are stuck. - Author: Alex Morgan - Tags: Ninja Gaiden Sigma, walkthrough, Action games, PS3, Golden Scarabs, #gce-f12559a9 This Ninja Gaiden Sigma walkthrough takes you from the first chapter to the last, with a route, boss approach, and survival tips for each stage. Sigma is Ryu Hayabusa's first foray into the PS3 world, and the guide covers all 19 chapters of the game [\[1\]](https://www.ign.com/wikis/ninja-gaiden-sigma?ref=idleweekend.net). The guide is built for the PlayStation 3 release, so its chapter flow matches that version [\[2\]](https://gamefaqs.gamespot.com/ps3/935677-ninja-gaiden-sigma/faqs/49145?ref=idleweekend.net). Use it as a reference for that game rather than a general Ninja Gaiden guide. When you get stuck, jump straight to the chapter you are on and read its boss and survival tips before the fight. The guide also lists all 50 Golden Scarab locations, so you can go back for a full collection once the story is done [\[1\]](https://www.ign.com/wikis/ninja-gaiden-sigma?ref=idleweekend.net). ## How are the 19 chapters laid out? The walkthrough covers all 19 chapters of Sigma from start to finish, so you can read it straight through or jump to the stage that is stopping you [\[1\]](https://www.ign.com/wikis/ninja-gaiden-sigma?ref=idleweekend.net). Most players will use it as a reference, and the chapter list is the fastest way to find your place. Each chapter gets its own combat notes and boss approach. That means you can skip ahead without missing a required fight, because you don't need to read the earlier stages to handle the one you are stuck on. ### Find your stage quickly Scroll the chapter list rather than reading in order. Pick the chapter where you lost progress, read its combat and boss notes, then go back to the game. Think of it like a field manual. Say a boss keeps knocking you down near the end of a chapter. You can read that one entry, try the fight again, and skip everything you have already beaten. The same approach works for a regular fight that keeps going wrong, since the combat notes sit in the same chapter entry. ### Why the story matters less here The story opens with Ryu infiltrating the Shadow clan fortress to visit his uncle, the clan leader Murai [\[1\]](https://www.ign.com/wikis/ninja-gaiden-sigma?ref=idleweekend.net). That background is worth a read once, but you don't need to replay it every time you reload a stuck fight. Read the chapter section before you start the stage, not partway through a fight. Pick out the one or two tactics that apply to the enemies you are facing, then try them on your next attempt. If you hit a new problem later, return to the same chapter entry. Because each chapter stands on its own, you can start the next stage without rereading the earlier ones. ![An open notebook on a desk holds a hand-drawn stage map, with a pencil and game controller resting beside it.](https://tse1.mm.bing.net/th?q=open%20notebook%20with%20hand-drawn%20stage%20map%20beside%20controller&w=800&h=450&rs=1&c=4) ## What combat basics and power-ups matter most? Start with the basic combat section of the guide. Learn how your attacks work and how enemies react before you try anything fancy. The guide covers Combat and Advanced Tactics as separate topics, so you can work through them in order [\[1\]](https://www.ign.com/wikis/ninja-gaiden-sigma?ref=idleweekend.net). Move on to advanced tactics only after the basics feel natural. Early on, your goal is to stay alive, not to string together long attack chains. Once you can clear an ordinary room without taking heavy damage, the advanced section helps you handle bigger groups faster. ### Power-ups and enemy types The guide also covers power-ups and enemy types in detail [\[2\]](https://gamefaqs.gamespot.com/ps3/935677-ninja-gaiden-sigma/faqs/49145?ref=idleweekend.net). Read those entries before a tough chapter, so you know what you are picking up and what an enemy can do before it surrounds you. For example, if a group of enemies keeps closing in on you, look up each enemy type first. Knowing which one hits hardest lets you decide what to take out first. ### When a regular fight keeps going wrong If the same ordinary fight keeps beating you, change one thing at a time. Use the combat notes to adjust your approach: try a different attack pattern, move to a narrower space where fewer enemies can reach you, or wait for an opening instead of rushing in. For example, if you keep getting caught by a group in an open area, retreat to a hallway and fight them one at a time. Try the new approach for several attempts before you switch again. That way you know which change actually made the difference. ![A person in a black ninja costume grips a sword in a dim forest clearing, mid-stance, ready to strike.](https://tse1.mm.bing.net/th?q=person%20in%20black%20ninja%20costume%20holding%20sword%20in%20forest&w=800&h=450&rs=1&c=4) ## How do you beat the bosses? The fastest way past a boss is to open its strategy entry in this walkthrough. The guide covers boss strategies alongside combat and advanced tactics, so the boss notes sit next to the basics you need [\[1\]](https://www.ign.com/wikis/ninja-gaiden-sigma?ref=idleweekend.net). Look up the boss you are facing rather than trying to work out its pattern on your own. ### Read the boss entry before you fight Read the entry before you start the fight, not after you have lost a few tries. A few minutes of reading lets you plan your opening moves and know what to watch for before the boss acts. Keep the key points in mind as you walk in, so you are not searching the page while the fight is already on. This matters most for bosses that are fast or punish one mistake. If you read the entry first, you already know which attack to expect and when to back off. ### Combine boss notes with the combat basics When a boss keeps beating you, the cause is often a basic habit rather than the boss itself. Go back to the combat notes and check how you are handling regular enemies, since the same habits carry into boss fights. Then return to the boss entry and try the fight again with those basics in place. For example, if you keep getting caught mid-combo, slow down and watch the boss's wind-up before you commit to an attack. Then use the boss entry to match that wind-up to the pattern it describes. Pairing the two usually works better than repeating the same attack and hoping for a different result. If one fight stalls you for a long time, switch from the boss notes to the combat material and back again. Each one fills in what the other leaves out. ## Where are all 50 Golden Scarabs? Ninja Gaiden Sigma has 50 Golden Scarabs spread across its 19 chapters, and the guide lists where every one is. [\[1\]](https://www.ign.com/wikis/ninja-gaiden-sigma?ref=idleweekend.net) If you want a full collection rather than just the story, use the scarab list as your checklist. ### Collect as you go It is easier to grab each scarab while you are still in the chapter where it sits. Once you move on, backtracking through earlier stages costs time. Work through one chapter at a time, and check that chapter's entry before you move on. [\[1\]](https://www.ign.com/wikis/ninja-gaiden-sigma?ref=idleweekend.net) A simple routine works well: 1. Clear the chapter's main route. 2. Open the guide's entry for that chapter. 3. Go back for any scarab you missed before you start the next chapter. With 50 to find, a running count keeps you on track. Note how many scarabs each chapter should give you, then compare your total against that number after each stage. ### Why the chapter list helps The guide is built around the chapters, so each one has its own set of locations. That means you never have to search the whole game for a single scarab. If you know which chapter you are in, you already know which entries to read. [\[1\]](https://www.ign.com/wikis/ninja-gaiden-sigma?ref=idleweekend.net) Use the same approach when you come back later. Pick a chapter you have already finished, open its entry, and check whether you have every scarab it lists. This takes a few minutes and is faster than replaying a stage from the start. ### When to use the list The list matters most when you want a full collection. If you only want to finish the story, you can skip it and come back later. Once the main route is done, the scarab entries give you a clear list of what is left to find. ## Can you unlock extra modes and achievements? Yes. The walkthrough pages explain how to find items and unlock modes, so you can go after the extras once the story is done [\[3\]](https://ninjagaidensigmawalkthrough.weebly.com/?ref=idleweekend.net). A separate achievement route covers how to earn all of the achievements [\[4\]](https://www.trueachievements.com/game/Ninja-Gaiden-Sigma/walkthrough/1?ref=idleweekend.net). Most players save this for after the main story. By then you know the chapters, bosses, and combat well enough to revisit tough fights without getting stuck on the basics. ### Unlocking modes and items Start with the item and mode pages. They show how to find the items and how to unlock the modes, so you can plan a second run instead of hunting blindly [\[3\]](https://ninjagaidensigmawalkthrough.weebly.com/?ref=idleweekend.net). Write down which unlocks you want before you replay anything. Keep your finished save separate if you plan to replay chapters. That way you can revisit a stage for one unlock without losing progress you already made. ### Working through achievements The achievement route is a different path. It is built around earning every achievement in the game, so it can send you back to chapters you already finished [\[4\]](https://www.trueachievements.com/game/Ninja-Gaiden-Sigma/walkthrough/1?ref=idleweekend.net). Use it when you want a checklist, and skip it if you only care about the extra modes. ### A simple order to follow 1. Finish the story so you know every boss and chapter. 2. Open the walkthrough's item and mode pages and note the unlocks you want. 3. Replay the chapters those unlocks require. 4. Switch to the achievement route for anything left over. Work through the list one chapter at a time. The second run usually feels easier, because you already know where the tough enemies appear and which fights you can move past quickly. ## What should you do after the walkthrough? Remember that you don't need to play straight through. When you get stuck, jump to the section for that chapter and read its approach before you try the fight again. Once the story is done, go back for the Golden Scarabs and unlocks. You'll find them easier to hunt without the pressure of the plot. Start with the scarab list and work through one chapter at a time. Keep the chapter list handy as a quick reference. It's the fastest way to find the stage you need, whether you're replaying a hard fight or tracking down one missing item. ## Sources 1.
