  • Small Bugfix Patch - 25 December 2022

    Fixed a problem that was causing a draw event error message for some players.

  • Sigma Impact Update - 23 December 2022

    It's out! There's still so much I want to add/tweak but the Winter sale is a good time to find a stopping place and put this thing out. Thanks again to everyone for playing this thing along with me, and especially to everyone on the Discord for the playtesting and bug reporting and suggestions and distracting me from work and support and just being good people to hang out and chat with. I'm still not very good at this whole development thing so the following list is based on my (poor) memory: Game Balance Everything from enemy spawn numbers and ai, a simplification of the player health system, new game+ scaling, weapon and perk adjustments... Everything from the ground up has been fine-tuned and adjusted over many, many play tests and iterations. I tried my best to make sure every player can find the right difficulty, from level 0 to ng50. I really feel that Sigma Impact offers an unmat…

  • Autumn Sale - 33% Off! - 24 November 2022

    Hey, I realized I forgot to sign up for the Autumn Sale on time. If you bought the game at full price, thank you!!! But to make it up, if you bought the game during the sale at full price let me know and I'll send you a key you can give to a friend. Thanks again! And please, go ahead and join the Beta version in Steam for the latest update. I've been working hard for the past ~14 months polishing and refining this thing, so that will definitely give you the best experience. I'm still working on a new trailer before I push the latest to the main branch. And join the Discord! https://discord.gg/JB96btVU

  • Looking for testers for new update! Discord server back up! - 16 October 2022

    Hi! Sorry for such a long wait, but the update I've been working on since release is finally ready to open up for public testing. You can find it in the Betas tab of the game properties in Steam. If you're interested, come by the Discord and hang out and leave some feedback! https://discord.gg/7mwvsSPqC4 This update is more of a refinement/re-balance of Sigma Impact rather than a big content update, more like a 1.0 release out of Early Access. I've polished the visuals, added to the music, tweaked all of the weapons and their specials, and added a few new ones. The mouse controls have been completely redone from the ground up. New Game+ has been re-balanced to be more fun, more forgiving. I've added a simple Daily Mode. It's been a little over a year since release, and I'm still so proud of what I've done with this thing. I don't have as much time to work on it (hence the size of this u…

  • Sigma Impact Testing Branch Available - 30 October 2021

    Just wanted to give a little update on my progress and announce that I've added a test branch if anyone would like to try the latest build. The only new things in the test branch are some big visual updates/optimizations, re-balance work on the jet hammer, and some bug fixes. I'd love to get some feedback on how the visual updates affect performance. I've heard some good things so far from the Discord. Development progress on the content update is still going slow but steady, I usually just have 1 or 2 days a week to really work on it so please have some patience with me. The new day job is still taking a lot of my energy. Anyways, thanks everyone for playing my game! I'm still kinda blown away by the feeling of being a developer and having other people play and enjoy something I've made.

  • September 6th Small Update/Developer Plans - 6 September 2021

    This small update has a couple new features/bug fixes which I'll list below but first I'd like to just say a couple things about my current work schedule and plans for the future of Sigma Impact. The past couple weeks since launch have been very hectic for me, bouncing around between 2 different jobs, being a single dad to a 6 year old, and trying to find time to get in some bug fixes. I'm starting a new full-time position tomorrow so I don't really know how long things will take to settle down so I can focus again on developing new content for my game. That said, I have plenty of ideas and suggestions from the community for things to add to a future content update, like new weapons, perks, enemies, types of level generation, variations for the boss, etc... If you have any ideas you'd like to share feel free to post on the forums or stop by our Discord (https://discord.gg/DPueTTwDG4) Th…

Price History Overview

USD uses SteamPulse's own locally recorded daily store snapshots, so this overview reflects the exact regional price history that SteamPulse has captured for this currency.

Coverage And Tracking Window

  • Snapshots: 1
  • Coverage: Sep 23, 2026 to Sep 23, 2026
  • Lowest observed: $4.99
  • Highest observed: $4.99

Sigma Impact's USD price history spans from Sep 23, 2026 to Sep 23, 2026, with 1 recorded snapshot across 1 calendar day. Each row records the available final price, listed base price, and discount metadata for that observation. Within this coverage the lowest recorded price is $4.99, the highest is $4.99, and the first visible tracked price is $4.99. These comparisons apply only to the snapshots SteamPulse holds; missing observations can contain changes that are not represented here.

For USD, SteamPulse uses locally captured regional storefront snapshots and does not reconstruct older prices with exchange-rate conversion. The chart and table show the values recorded for this exact currency from the stated coverage start. Additional snapshots extend that record, but they do not fill unobserved days or prove what the storefront displayed between observations.

Discount Windows And Sale Timing

  • Discount windows: 0
  • Discounted days: 0 days
  • Deepest markdown: No discount tracked
  • Latest sale window: No sale window tracked

Sigma Impact's tracked USD rows do not contain a discount window. This means no available snapshot in the stated coverage has usable discount metadata; it does not prove that the game was never discounted. Missing snapshots or archived rows without complete metadata can hide a sale, so SteamPulse does not infer pricing strategy from this absence.

If a later snapshot includes discount metadata, it will appear here with its recorded depth, price, date, and sale name when available. Until then, this section should be read only as a description of the available rows, not as evidence about the publisher's promotion policy.

Observed Price Changes And Stable Runs

  • Observed price drops: 0
  • Observed price rises: 0
  • Longest stable run: 1 day of uninterrupted daily tracking
  • Current run: 1 day of uninterrupted daily tracking

Outside rows carrying discount metadata, the tracked price has not recorded a separate price rise or drop yet. That means the observed undiscounted level has stayed stable across the snapshots SteamPulse currently holds. This is a statement about the recorded coverage only; it does not prove that an older or missing price change never happened.

The longest unchanged price stretch in the current record lasts 1 day of uninterrupted daily tracking at $4.99, from Sep 23, 2026 through Sep 23, 2026. Among rows without discount metadata, the longest unchanged run lasts 1 day of uninterrupted daily tracking at $4.99. The latest run records $4.99 for 1 day of uninterrupted daily tracking as the same recorded undiscounted price. Run lengths describe consecutive stored observations only and do not establish that a price is permanent.

Latest Snapshot And Sales Context

  • Current price: $4.99
  • Current list price: $4.99
  • Distinct observed prices: 1
  • Source mode: SteamPulse local tracking

The latest tracked snapshot records Sigma Impact at $4.99 in USD, with no active discount metadata. Across the available history SteamPulse has recorded 1 distinct final price in this currency. This supports comparisons with the lowest, highest, and most common values present in the retained record, subject to the stated coverage limits.

The live sales view and Steam sales record provide calendar context for these dates. A date overlap can be compared with a named Steam event, but it does not prove why a publisher changed a price. As new daily rows arrive, this overview recalculates its observed prices, discount windows, and run lengths automatically.
