Unit 4

Unit 4 comes at you with the kind of old-school platforming energy that is easier to enjoy with friends in the room. Its alien-invasion setup, playable heroes with different abilities, and local co-op for up to four people point toward a lively arcade game built for jumping into missions and making a mess together.

Retro Replay Review

Gameplay

Unit 4 opens with a strong throwback pitch: a frantic 2D action platformer where a team of heroes heads into space to recover a stolen artifact. That familiar framework is a good fit for an arcade-minded game. You are not here for a slow burn. You are here to move through strange missions, use each hero’s abilities, and push toward big confrontations.

Local co-op for up to four people is the feature most likely to make the game click. A group can turn even a rough patch into a funny shared recovery, and a roster built around distinct abilities gives the team concept more purpose than simply piling extra characters onto the screen. If you have regular couch co-op partners, Unit 4 has a clearer reason to exist than many solitary retro-styled platformers.

It is also a notably busy package. Space travel, exploration, unique missions, trading, minigames, and huge bosses all sit alongside the core platform action. That variety can keep a session from feeling routine, but it also makes Unit 4 feel less cleanly focused than the best games in the genre. Go in wanting an energetic grab bag of arcade ideas, not a lean precision-platforming classic.

Graphics

Unit 4 uses pixel art for its sci-fi action, giving the alien planets and quirky cast a deliberately retro game look. The small-scale style suits a brisk side-scrolling adventure and helps the game feel connected to the arcade platformers it is clearly chasing.

Story

The plot begins with an alien army stealing a sacred artifact during an invasion of the heroes’ home. It is direct, functional motivation, but it gives the journey a welcome sense of urgency: recovering the artifact matters because the wider solar system is in danger.

From there, the story leans on a simple mystery. Who are the invaders, what do they want, and can the team get the artifact back before disaster spreads? Those questions are more useful as momentum for the adventure than as a promise of elaborate science-fiction drama.

Quirky characters and a trip across the solar system give the premise some personality. Still, the narrative sounds strongest when treated as a lighthearted excuse to keep moving from one challenge to the next. You should come for the action and the company, with the invasion mystery as a pleasant extra.

Overall Experience

Unit 4 has the right instincts for a casual game night. Its four-player local co-op, fast platform action, and broad assortment of activities create plenty of room for a group to find its own rhythm. The game is more inviting when you can share the confusion, discoveries, and victories with other people.

Solo players may find the sprawling list of ideas harder to embrace. When a platformer also reaches for exploration, trading, minigames, and travel between locations, the overall experience depends on whether that constant change feels playful or distracting to you. Unit 4 favors variety over a single-minded structure.

That makes it a decent recommendation for couch co-op fans who miss the simple pleasure of working through an action platformer together. It is less essential for anyone looking for a sharply polished genre standout, but its offbeat sci-fi premise and team-first design give it enough character to be worth a look. For basic game details, the Unit 4 official site is a useful starting point.
