A top-down wave survival shooter with weapon upgrade combos and online co-op, but zero review traction after six years on Steam tells you most of what you need to know before clicking buy.

My first instinct looking at ZombieThon is that it wants to scratch the same itch as those late-night horde-shooter sessions where you and a friend grind through escalating waves until the screen turns into pure chaos. The concept is solid enough: a top-down arcade shooter built around survival missions, infinitely scaling zombie waves, and a weapon upgrade system that layers on bonuses as you go. Bouncing bullets, split-shot, and a handful of wilder special abilities give the upgrade loop some surface-level appeal. Unlockable characters per level add a thin reason to replay. On paper, this is a passable couch-or-online co-op time-killer. The problem is the execution gap. GreenThumbStudios themselves admitted, in a 2021 update post, that the game shipped with poorly optimized visuals and clear gameplay flaws, and pledged a full overhaul. That kind of developer transparency is worth something, but it also means you're buying into a title that launched rough and has had very limited public post-launch activity to show for it. No Steam reviews exist. No Metacritic score. The community hub is essentially a ghost town. For a multiplayer-focused shooter, an empty player base is a structural problem, not a cosmetic one. Online PvP and online co-op modes mean nothing if you can't populate a lobby. From a pure shooter-mechanics standpoint, the things that matter to me - netcode quality, time-to-kill tuning, weapon balance across upgrade paths, and whether ranked or leaderboard competition has any teeth - are impossible to evaluate from the outside. The Steam Leaderboards feature is listed, which suggests at least some score-chasing infrastructure exists. The character abilities angle could add genuine build variety if the unlockable roster is designed with differentiation in mind rather than cosmetic reskins. But without a player community stress-testing those systems, all of it stays theoretical. Solo players get a dedicated single-player mode, and the infinitely scaling wave structure means there is technically no ceiling on how hard it can get. If you want a low-stakes top-down bullet-hell horde shooter to play in short bursts, the bones are there. Just know you are walking into something with very thin community infrastructure, an unclear post-overhaul status, and no critical baseline to calibrate expectations against. The PvP side in particular feels like a feature that exists on paper only at this point. Fred, Scout Team

Hard to recommend over better-supported alternatives unless you find it in a bundle and have a co-op partner ready to go.
