  • Oppcium - Build 11251 - 20 March 2022

    Hello. It has been a while since the last update. Life got in the way and I had to focus on other stuff, but I am back now and ready to work some more on Oppcium. For now, I decided to work more on the first chapter of the game and polish, add new mechanics, make the game the best it can be. I will continue to closely monitor feedback and adjust the game in order to make it more interesting and easy to get into. Without going too much into detail, here's what the new update has to offer: Build 12251 - Patch Notes: - A yellow beacon is now hovering over all lore items. - Added more tooltips in the "Controls Menu" that state that you can check if you have any grenades by looking at your belt. - A sound has been added whenever an in-game notice appears on the top-left corner.

  • Oppcium Update Build 11248 - Patch Notes - 16 December 2021

    Oppcium Update Build 11248 - Added map markers in the game. This change was added to give players more guidance and to ensure they always have a clear goal. This change was also mainly implemented to make the game more enjoyable and more accessible. The map markers are now present on the Map and they will guide the player from the start of the game to the end. - All map markers have a tooltip related to what you have to do at a specific location. - The game will always notify the player when a new map maker is added. Keep in mind that this change did not take out much of the difficulty of the game, it was never meant to come from puzzles, but from enemies. - New voice lines were implemented into the game. - Fixed a bug where Specimen-01 could not see the player properly when hiding in the courtyard behind the grassy squares with the animal statues in the middle. - Added a map to the ins…

  • World's First & Contest - 11 December 2021

    Hello. I am making this post, first of all, because someone finished the first chapter of the game. Which is quite a surprise for me. I did not expect someone to finish it in the first week of the launch. I was expecting somewhere between 3-4 weeks. The reason behind that expectation is because of how hard the game is and how much patience, dedication, and improvisation it requires in order to finish it. I was wrong! With that being said, it's awesome to see someone finish the product that you worked on so hard and for such a long time. It's why I made this game! Don't expect this to be all the Oppcium will have to offer in the future. Stealth is a core mechanic, yes, but the game will have intense action scenes, mini-games, weapons, more enemies, and other stuff that I do not wish to spoil. I'm going to leave a SPOLER ALERT and link the video: https://www.youtube.com/watch?v=FNl9Fpj0kE…

  • Oppcium Update Build 11247 - 9 December 2021

What to expect by next week: - Map objective markers. - DEMO.

  • Oppcium Update Build 11244 - 7 December 2021

    Oppcium Update Build 11244 - Patch Notes - The lighter's duration is increased from 10 minutes to 100 minutes. - Better player guidance is added at the beginning section of the game. - Fixed the lighter text inside the inventory. What to expect in the coming days: - A map. - A demo.

  • Before You Buy - 5 December 2021

    Hi. Before you decide whether or not to buy the game, you can have a look at the intro of the game from a YouTube Channel called AllGamesWorldHd. The channel is a Steam Curator and I did not give him any tips on how to play the game or what to do. But the gameplay he shows works perfectly because you still can't see what you are up against. I want that to be a surprise for players. Thank you for showcasing and playing the game @AllGamesWorldHd! More gameplay: Thank you Addmai01!

  • Early Release - 5 December 2021

    Hello. I am making this post to let you know that I decided to release the game earlier than it was planned. The only problem with the launch is the steam achievement system. It does not work for one reason or another but I am looking into it. Othan than that the game should work as intended and shouldn't have any other issues. Good luck with your investigation!

Short description

A sentient alien organism has escaped its cage and now freely roams a government facility. Silence has engulfed the city as a toxic and unidentified cloud was released from black oily stones. Witness and investigate a dire situation that appears to escalate by the hour.

Steam marketplace comparison data

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: $3.99
  • Highest observed: $3.99

Oppcium'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 $3.99, the highest is $3.99, and the first visible tracked price is $3.99. 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

Oppcium'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 $3.99, 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 $3.99. The latest run records $3.99 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: $3.99
  • Current list price: $3.99
  • Distinct observed prices: 1
  • Source mode: SteamPulse local tracking

The latest tracked snapshot records Oppcium at $3.99 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.
