About ZombieThon
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
