Compare Hyper Sentinel prices across trusted key stores and find the best deal. Developed by Four5Six Pixel. Published by Huey Games. Released on 5/10/2018. Available on PC, Mac, Linux, Xbox. Genres: Action, Indie.

If the words Uridium or Defender still carry weight for you, Four5Six Pixel built this one specifically for your nervous system. Everyone else gets a solid, frantic shmup with honest arcade bones.

I kept coming back to one thought while piloting through Hyper Sentinel's 12 dreadnaught stages: this game knows exactly what it is, and it has zero interest in apologising for that. It is a spiritual revival of the 1986 Commodore 64 shooter Uridium, Kickstarter-funded and crafted by solo developer Jonathan Port under the Four5Six Pixel banner, with publisher Huey Games carrying genuine lineage to the original game's legacy. That context matters, because it explains both the game's greatest strengths and its most visible ceiling. The core loop is a left-right scrolling affair where you sweep your Sentinel-class fighter over enormous armoured Super-Dreadnoughts, picking off surface turrets and enemy formations before each stage closes with a multi-stage guardian boss. The direction flip mechanic is the quiet star here: flicking your ship to reverse course grants a split-second of invincibility, a window that turns every directional change into a micro-decision under pressure. Power-ups scattered across the dreadnaught surfaces add real variety to individual runs. The Astro Mace, a chain of three rotating balls dragging behind your ship, feels genuinely different from the Plasma Rifle or Arc Streamer, and chasing those pickups while dodging cannon fire is where the tension lives. Three difficulty modes, including a punishing Retro setting, and three separate mode structures (Arcade, Survival, and Boss Run) give completionists around 60 medals to chase plus online leaderboards to obsess over. A full Arcade run sits under 45 minutes, which means the replay loop is the point. Where the game runs into friction is structural rather than mechanical. The 12 stages are undeniably samey in layout, the threat variety shifting mainly through enemy colour swaps and minor formation changes. That sameness was a hardware limitation in 1986; in 2018 it reads as a deliberate design choice, and your tolerance for it will determine almost everything about your experience. Critics noted the repetition fairly consistently across review coverage. The Survival mode's time-based scoring, rather than kill-based, also felt like a missed opportunity to add a second dimension to score-chasing. And there is no multiplayer at all, which stings for a game that radiates the spirit of two-player arcade cabinets. Visually, the pixel art is punchy and fast rather than painterly. Stars streak in foreground and background layers to sell the speed, and the whole thing holds a locked 60fps without complaint. A CRT filter, a ZX Spectrum mode, and a Commodore 64 palette option sit in the settings for the deeply nostalgic, though they function more as novelties than genuine play modes. The chiptune soundtrack and sampled speech knit together well, carrying that particular frequency of 8-bit home computing that either clicks something into place for you or simply does not. If it does, the soundscape becomes part of the appeal in a way that is hard to explain to someone who did not grow up with it. Hyper Sentinel sits in an honest middle space. It is not a genre-expanding release, and the small Steam review pool (sitting at a positive ratio, though limited in count) reflects a game that found its intended audience without crossing over much further. For a player who wants 20-minute burst sessions with genuine scoring depth and a feel for classic horizontal shmup design, it earns its place in a library. For anyone hoping for the structural breadth of a modern arcade release, the seams show. Kai, Scout Team

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
