Sigma Star Saga DX is an enhanced version of the original 2005 Game Boy Advance (GBA) game by Wayforward. The sci-fi game carries a unique mix of genres with improved enhancements, though it carries some minor hiccups, it makes a fine addition to your gaming library.

A Galaxy in Trouble

You play as Ian Recker, an ace human pilot who is sent undercover to join the Krill Empire, a kingdom run by an alien race called Krill, that is in combat with Earth over a “special weapon” that has the power to destroy planets. As a double agent, you’ll explore planets and interact with various characters to uncover secrets from both the human and Krill races through five chapters of intriguing events.

Sigma Star Saga script is filled with betrayals, shifting alliances, and its romantic elements between two female characters makes it an intriguing and engaging story to follow. It’s watching a sci-fi film but in the hands of the player to uncover. The dialogue feels original with a touch of humor and a splash of personality, keeping players engaged and eager to uncover the next twist of each chapter. While there may be some corny dialogues, they add charm and personality to the main and supporting characters. With the game offering multiple story endings, it encourages players to experience them all for the full experience of the story.

A Unique Specimen

The classic GBA game brings its unique style to the latest version, featuring top-down role-playing game (RPG) exploration with action elements and side scrolling shoot-em-up mechanics for space battles. Visually the space battles resemble classic games like the Radius and Cotton series but are treated as random encounters like many RPG titles. Instead of gaining power-ups during battle, you earn experience points (EXP) by defeating enemies. Leveling up improves your character’s health, attack, and defense. To upgrade your ship, you need to find Gun Data, which includes over seventy different items that can be found while exploring planets. These items can enhance your abilities in battle, such as shooting more projectiles or creating barriers upon contact. Leveling up also replenishes your character’s health to full. In this enhanced version, frame rates do tend to dip when there’s a large amount of projectiles shooting from both sides of the battlefield or when dropping a bomb to take out foes around.

Throughout the game’s story, your character will receive tools to aid in exploration, such as a Scanner to locate hidden triggers and items, Krill Boots to run faster and impact triggers to open paths, and gain wings to fly across specific areas. Each mission on foot provides a map with pinpoint locations to guide you, making missions easier to navigate. The maps offer a basic boxed area without further detail, as the split paths can lead to the same area, making additional details unnecessary. Enemies will roam these areas and approach you when spotted. Breaking statues with your pistol can yield rewards like health kits to replenish depleted health, aiding in your exploration. However, you do not earn experience points while exploring on foot.

Take it Higher

Battles occur randomly while exploring on foot, sending you to your spaceship for side-scrolling battles. Each battle requires you to shoot down a certain number of enemies, and your ship setup, such as projectile styles, carries over between battles. Once completed, you return to your exploration. Random battles do not occur within spaceships and caves. Certain parts of the story will have you take flight from the current space station to face a powerful enemy, navigating through space without the requirement to shoot down a certain number of enemies. However, the goal is to survive till the end. For example, you’ll encounter tight tunnels or various objects to fly around to prevent damage. If your health gauge depletes completely, you’ll receive a Game Over screen with the option to continue or quit. Whether you return now or later, the game will bring you back to your last save point if you use the original game’s system and not the enhanced options of loading anywhere.

Sigma Star Saga battles and explorations differ from traditional shoot-em-ups and RPG titles, blending mechanics together for a unique experience but still deteriorates its flow in the DX version. While exploring, random battles can disrupt the flow and occur more frequently than desired, despite modifications in this enhanced version. Backtracking is common, and the occurrence of random battles may test the player’s patience. Those who’ve played the original GBA version would see a difference but newcomers may still feel the overwhelming amounts of battles while trying to figure out where to go to initiate the next story event.

Adding a quality of life feature to adjust the frequency of random battles, similar to Mega Man Star Force Legacy Collection, could improve gameplay flow. This option could be unlocked after completing the game on the same save file, allowing players to choose whether to engage in all random battles to prepare for story-driven encounters.

When players return to play the game on the completed game’s save data, Gun Data and ship customizations are carried over, giving players a head start with less frustration. However, story progression, exploration tools, and character levels are reset. Collecting all Gun Data is crucial for unlocking a different story ending. With multiple story endings available for players to uncover, it’s hard not to be motivated to explore all the possible ways Sigma Star Saga ends.

A Refined Upgrade

Originally, the game’s storytelling carried pacing issues that were difficult to follow, but in the enhanced version, it feels polished and easier to follow while carrying the game’s original content while keeping the main story intact. Not only was the dialogue smoothed out, but additional gameplay mechanics were also tweaked for a smoother ride. Thanks to feedback from fans who played the original GBA game, Wayforward made adjustments to improve gameplay and other mechanics.

The navigation/map setup, additional save points, rebalanced EXP system, improved hitboxes, random encounter amounts, and more were adjusted in this enhanced version. The game feels more satisfying and smoother. Battles no longer have difficulty spikes, and players can engage in battles without worry. While battles are easier to engage in, some battles may feel too simple depending on the ship adjustments players have made.

In addition to extra save points, the DX version includes a new game menu where players can save anywhere with only the current save data, volume control, sidebar graphics, and a few other minor settings. One of the biggest additions is the rewind tool. Made a simple mistake during a boss battle? Now you can rewind it and bypass the error you made. If possible, a setting for random encounter frequency could be added here.

The graphic visuals maintain the pixel-art style from the original GBA, which still resonates with today’s games that seek a classic retro look. Character illustrations in dialogues are still pixel-based, though cleaner illustrations could benefit the enhanced version. Characters themselves look great visually when exploring, with smooth animations. The soundtrack still captures that classic chiptune sci-fi vibe with electronic scores. It adds a mysterious tune when transitioning between chapters and lively scores during exploration. It truly enhances the retro feel of the game and makes exploration enjoyable.

The Final Mission

Sigma Star Saga DX delivers an engaging sci-fi story with charming characters, improved quality-of-life upgrades, and strong replay value thanks to the game’s multiple endings. There’s a few battle hiccups such as frame rate dips but this retro-style adventure still shines as a unique journey that’s worth exploring for both newcomers and veterans. A must-play for fans of classic GBA adventures.
