Invasion Protocol is a top-down roguelite shooter built around insect swarms, short objectives and weapons that can be changed during missions. The concept is clear and playable. Its current version, however, offers too little content for an unconditional recommendation.
GoldenGod Games sells the game on Steam in Early Access. The official page presents a solo or local co-op experience for up to four players, six classes and unlock-based progression. It also states that only one difficulty level and one map type are fully playable at this stage. That limitation should shape expectations from the outset.

A shooter built for short, frantic runs
You land on an infested planet, choose a soldier and clear areas under a barrage of projectiles. The advertised objectives include base defence, queen hunting, ship repairs and extermination. This variety could create a livelier rhythm than a straightforward survival arena.
Weapon crates and skill stations allow players to alter their arsenal during the action, while swarms and bosses are designed to increase the pressure. The foundation suits brief, hectic sessions. Official information is not yet sufficient to assess weapon balance, enemy behaviour or the long-term feel of the controls with confidence.
Six classes, with depth still unconfirmed
Soldier, Officer, War Engineer, Infiltrator, Explosives Expert and Zoner: the six announced archetypes suggest different play styles. In a roguelite, that diversity can help renew a single map more effectively than a larger rifle catalogue. Four classes are unlocked through progression, however.
The Steam page also promises weapons and skills to swap during a run, followed by new unlocks after each run. The progression therefore has the right ingredients on paper. Planned difficulties, events and terrain variations are not all available yet, so its actual depth remains to be demonstrated.
Early Access puts a limit on longevity
GoldenGod Games says Early Access is intended for testing, balancing and improving gameplay comfort. The studio initially planned three to four additional months of development, with more maps, events, unique abilities and terrain variations.
That schedule is not a guarantee. Steam also had too few reviews to display an overall rating at the time of public verification. A feature list cannot therefore establish replayability. For a couch gaming night with friends or family, the modest price can be justified. For a roguelite intended to occupy dozens of hours, waiting for measurable additions looks wiser.
Light requirements, limited technical evidence
The official minimum requirements are very light: a 2 GHz processor, 512 MB of RAM, 300 MB of disk space and a graphics card with 128 MB of dedicated memory on Windows. Steam also lists a SteamOS/Linux version, with a minimum graphics requirement of 512 MB.
Those figures suggest accessibility on modest hardware, but they do not replace stability testing. The page gives no frame-rate target, resolution details or Steam Deck validation. Because the visuals show many enemies on screen, more evidence is needed before promising consistently smooth performance.
A dark visual identity that still needs variety
Skull-shaped helmets, a hostile planet, insects and gunfire flashes: the setting is deliberately unsubtle. It has an identity that fits the brutal arcade action, while the top-down perspective appears to prioritise silhouettes and trajectories when the screen fills with targets.
The same aesthetic could become repetitive if environments diversify slowly. The developer specifically lists additional terrain and locations among the planned additions. For now, that is a point to monitor rather than a definitive flaw.
Local co-op is the clearest reason to buy
Invasion Protocol is offered on Steam for $9.99, at the price displayed on the verified US store page. It is available on Windows PC, and Steam also lists SteamOS/Linux in its system requirements. No console port is announced on that page.
The strongest argument today is local co-op for up to four players. Steam also lists split-screen, Steam Cloud and Remote Play Together. With a ready team, the chaos of a swarm shooter may be genuinely enjoyable. In solo play, the lack of content is harder to overlook.
Solo players have more reason to wait
The studio acknowledges that the game still needs balancing, comfort improvements, events and maps. The limited public feedback is another constraint. A low review count does not prove that the game is poor; it simply makes it difficult to determine whether it holds up beyond the opening sessions.
The Steam page does not list French: the interface, voices and subtitles are marked as English. For a highly visual shooter, this may not be decisive, although objectives and settings can still require basic comfort with the language.
Verdict: a small co-op game worth watching
Invasion Protocol has a focused proposition: a fast-paced roguelite shooter with classes, equipment crates and insects to eliminate. Its moderate price limits the financial risk. This Invasion Protocol review remains cautious because the current version lacks officially acknowledged variety and public feedback is still scarce.
Buy now if you want a local action game to share and accept Early Access uncertainty. Wait for an update if you mostly play alone, want a substantial roguelite or expect documented performance. Before buying, consult the official Steam page and the Steam Early Access FAQ.
