Hard-as-nails retro platformer with a four-character swap gimmick that actually has teeth, but control jank and a punishing camera will test your patience before they test your skill.

I came into Unit 4 expecting a cheap couch co-op throwaway and left with a mixed bag that took more out of me than I expected. The core concept is genuinely interesting: four characters, each locked to a specific ability set, and you cycle through them on the fly to clear levels that demand all of them. Blue double-jumps and wall-slides, Red shoulder-charges through obstacles with a Deadly Dash, Green throws out a grappling hook to snag platforms or enemies, and Yellow ghosts through solid walls and stuns targets by passing through them. Solo, you are literally all four of them at once. That is a clever design hook and it does hold up during the better sections of the campaign. The problem is that Unit 4 pitches itself as a precision action-platformer, the kind where dying is expected but each death teaches you something. Celeste. Super Meat Boy. That tier. It does not reach that tier. The controls carry a mushiness that becomes noticeable the moment difficulty spikes, and the camera has a documented habit of not panning fast enough to show you hazards before they kill you. Cycling characters mid-air in a tight corridor feels cumbersome rather than slick, and a game built around split-second swaps cannot afford that. The jump arc carries a half-committed momentum that some players adapt to, others never do. Checkpointing is sparse enough that long level stretches wear you down before any sense of mastery kicks in. Co-op is where Unit 4 finds more of its personality. Up to four players local, each controlling one character, turns the synergy system from a solo juggling act into actual teamwork. When someone dies they float as a disembodied head, controllable, waiting for the team to give them a safe landing zone to rejoin. That is a smart co-op resurrection mechanic that keeps everyone in the action instead of spectating. Note that co-op setup on PC is slightly fiddly: only one player can use keyboard, controllers must be connected before you hit the title screen, and the game will not prompt you clearly if setup fails. Worth knowing before you sit down with friends and spend ten minutes troubleshooting. Content-wise there is more here than the price point suggests. Fifteen planets across three worlds, six boss fights, a galaxy-map overworld you navigate by ship, unlockable minigames, coin-purchased costumes, and ship decorations that include some knowing pop-culture winks. The 8-bit aesthetic and looping synth soundtrack are competent rather than memorable. Steam reviews land in mixed territory, hovering around 64 to 66 percent positive from a small pool, which tracks with the experience: players who vibe with its particular brand of old-school stubbornness find something to love, everyone else bounces off the controls. If you have a couch, three controllers, and friends who think Mega Man is too easy, Unit 4 gives you a legitimate evening of loud, argumentative co-op. Solo, it is harder to recommend unless you are specifically chasing the character-swap puzzle-platformer niche and can forgive a game that never quite nails its own control spec. Fred, Scout Team

GamerScout Verdict

Best for couch co-op groups with retro platformer patience; solo players need high frustration tolerance to get anything out of it.
