Story
In this revamped GBA game, you take control of a hero named Ian Recker, who must serve as a double agent of the Krill, an alien race increasingly hostile towards Earth and their human population. What starts as a pretty typical “investigate this army from the inside” job quickly turns into a multi planetary adventure, with more twists and turns than you might expect from your average Wayforward game…
Yep, this is a DX version of a GBA game from the mid 2000s. Published by Namco back in the day, Wayforward managed to get this out as yet another Carbon Engine reissue, based off their own GBA remix they put out a few months ago. The story is the same as the original game, and it definitely got me more interest than most Wayforward plots tend to, and comes with a lot of QOL features within the game itself, plus your usual Carbon Engine bonuses. Definitely a case where you want to actually take in the story here. There’s even multiple endings here!
Presentation
Being a Carbon Engine reissue, this one starts off in a menu with your typical features; a sound test, a gallery, and some options. The main menu here even has a unique vocal theme for this release.
The sound test is self explanatory, and the gallery includes a surprising amount of concept art and even some prototype concepts for the original game. For once, you actually don’t get any manual/box scans, neither for the DX version or the original Namco release, so you’re outta luck if you wanted to read the GBA manual here for any particular reason. Still, the concept art gallery is pretty cool and offers sprite sheets and other fun stuff to look at, even if it does contain some minor spoilers in the process, so be wary.
For the game itself, it sure looks like a GBA game, with the usual menu/sprite styles from mid 2000s Wayforward, and even character designs/key art on par with what they did at the time. Very nice looking sprite design, and very solid music for the GBA. Not a Virt score, but still a pretty good one and way more memorable than what Risky’s Revolution got years later. You have your usual screen size/filter/border options here too and I found them to work quite well.
Gameplay
Starting the game up, you have your usual rewind and save state features, but also the ability to just stick to the in-game saves if you choose to do so. That’s how a lot of these Carbon Engine releases tend to go, but some of those early Wayforward ones had saving quirks with in-game saves and I’m happy to report no such thing exists here.
Sigma Star Saga is a weirdo hybrid of multiple flavors, and it took a while for me to get used to the flow of it all. You start off in a basic horizontal shooter for an intro stage, then do a good amount of top-down, Zelda-esque stuff including basic combat. Finally, once you’re on a proper planet for the core gameplay loop, you get shown the two flavors meshing together, and see where those DX additions kick in.
The main gimmick here is that this is a Shooter X Action RPG hybrid, and how that works is you explore one of multiple planets on foot via an overhead view, using your arm gun to take out enemies and gain basic experience from them, while every now and then being summoned by your ship for a short, and I mean really short horizontal shooting section. Take out those enemies and you return to the ground, and that’s the core game loop.
It felt quite jarring to get used to at first, and that was before I found out DX made a lot of changes that made what was mildly annoying to me way better than what would have infuriated me have I grown up with this in my GBA kid years; see, those horizontal segments are done by random encounter like a turn based RPG, and no amount of menu and rewind scumming will save you from having to go through one of them once you hit the step total. They aren’t too outta hand, and that’s because the encounter rate is reduced compared to the GBA original.
If these random encounter battles were more varied and slightly longer, I’d genuinely not mind them and would even deliberately start multiple encounters in a row just for the fun of it, but a lot of them are real short, real basic, and real boring. The encounter rate as-is is just tolerable enough to the point they don’t drive me insane, and it helps you gain a good amount of EXP for clearing each shooter segment, which is another change from the original GBA version. More EXP, means more leveling, means you grow stronger quicker and actually feel your character grow in a satisfying manner and thus see your ship improve as well. It helps make the encounters not feel like a waste of time, which I appreciate very much as a QOL change.
So while the random encounters are short and kinda dull, it’s the little things which help make Sigma Star Saga DX pretty fun. Finding a new gun part to customize your ship with, going off the beaten path slightly to gain some extra EXP, find a hidden switch, or using a helpful tool to make more headway, and doing the main missions of each planet, which get you in a shooter stage of an actual significant length to them.
This is when I consider the shooting aspects to become more enjoyable, since your Gun Data can be used to determine how and where you shoot your ship’s weaponry, and you have three types of data to equip, with Cannon, Bullet, and Impact types. Keep picking up Gun data over the course of your adventure, and you’ll find yourself with a pretty good variety of combinations to play around with here. In these horizontal shooter stages, you have your typical shot and bomb setup, with said gun data determining how those shots will pan out. Once you find something you’re comfortable with and get into the swing of things, these shooter segments are pretty easygoing, since they play a lot like your typical horizontal shooter, with bombs being used to clear the screen and deal major damage to bosses, and your ship having a health bar that serves as your one life for the shooter section, but can endure multiple accidents like crashing into surfaces or getting hit by enemy fire.
Really if you have any slight experience with a tough horizontal shmup, these segments are fine, and pretty darn fun. Otherwise expect to use that rewind feature quite often, since these bigger levels have bosses at the end of them, which put your skills to the test and are fairly fun to fight. Of course, your increased experience helps out in these segments just as much as they do for the ground combat, so hunting for extra EXP to gain some max health for the boss fights isn’t a bad strategy if you feel the need to do so. Each new planet has its own share of enemies for both styles of gameplay, so you don’t just fight the same kind of grunts for encounter battles either, and you even get moments where you have to fight a boss enemy in the top-down view every now and again. All in all, pretty decent gameplay variety.
Conclusion
Overall, I really did enjoy the hybrid style of Sigma Star Saga, even if it was messier than I expected it to be and takes a while to get used to. The story was much more interesting than I thought it would be, and will be a to-do thing I’m pinning in the back of my mind to finish all the endings at a later date, since I’m definitely intrigued to find out more of what happens and that’s really the ultimate motivator to keep going in Sigma Star Saga above everything else. The DX QOL here is really useful and i’m happy I started with this version over the original, since the random encounter battles are far too simple for me to enjoy being randomly interrupted to do, and having that be more frequent would have driven me insane.
It’s such a shame too, since the bigger shooting stages are pretty darn fun, even if they pale compared to your Gradius and R-Types of the world. The top-down segments might also be simple and no Minish Cap, but they were enjoyable enough for me to keep playing them and not get frustrated, and the improved EXP gain helps a lot with learning the ropes of this game and not getting frustrated. The tools being pretty fun to use was also a nice surprise, even if Ian’s tool kit isn’t as impressive as anything Link would carry. All in all, this was a weird hybrid that took a few tries to click for me, but I was more than happy once it finally did so, and I feel this is a solid enough time for GBA fans. Definitely has a story you will be surprised by!
I give Sigma Star Saga DX a 7 out of 10.
