April 2026 is shaping up to be a thrilling month for co-op and multiplayer enthusiasts, with a lineup of games that span a variety of genres and styles. From urban RPGs to creative party games, this month’s releases focus on bringing friends together for unique adventures. Here’s a detailed overview of the top seven titles you can dive into this April.

1. Outbound

Releasing on April 23, Outbound is a calming and customizable co-op experience. Designed for up to four players, this game revolves around a shared journey in an electric camper van. Starting from scratch, groups customize and upgrade their van, transforming it into a mobile home by adding workstations, gardens, and decorations. The beauty of Outbound lies in its sandbox mode, emphasizing exploration over objectives. Players drive, scout for resources, and enjoy relaxing moments together. The game offers no survival mechanics or combat, making it perfect for unwinding with friends. However, Outbound lacks crossplay; you’ll need to stick to the same platform when teaming up. It will launch on both PC and consoles.

2. NTE

Nicknamed "Anime GTA," NTE is a free-to-play urban open-world RPG that blends supernatural elements with a vibrant cityscape. Designed for up to four players in co-op mode, the game features flexible opportunities for collaboration. While the main story is single-player, the moment you step into the open world, co-op possibilities unfold. Activities include street racing (either competitive or cooperative), arcade-style mini-games, fishing, and decorating personal apartments. For a more structured experience, there’s a heist-style mode and dungeon-themed missions. The game also includes chaotic elements similar to GTA's heat system, such as police chases and group escapes. NTE features a gacha system but attempts to minimize typical frustrations by improving base rates and eliminating weapon banners. Currently, the game is one of Steam's top 20 most wishlisted titles.

3. Last Flag

Launching on April 14 for PC, Last Flag takes the classic capture-the-flag formula and reinvents it by blending it with hide-and-seek mechanics. This 5v5 team-based shooter allows players to strategically hide their flag anywhere on the map before matches begin. The gameplay emphasizes teamwork, with roles such as flag runner, scout, defender, and healer available. Unlike many games in its genre, Last Flag doesn’t tie roles to specific heroes, offering more flexibility in playstyles. With voice communication, matchmaking, and no in-game microtransactions, the game provides a polished experience. Console versions are planned for release later in the year.

4. KILN

KILN stands out as one of the most creative party games of the year. Developed by the same studio behind Psychonauts and the Day of the Tentacle remaster, this 4v4 brawler brings pottery to life. Players craft their own vessels—bowls, vases, teapots, and more—adding strategic depth to the gameplay. Larger pots make durable tanks, while smaller creations offer agility. Matches involve smashing enemy pots, gathering water, and dousing the opponent’s kiln to win. Beyond gameplay, the crafting mechanics allow players to design and share unique pottery pieces online. KILN will be available through Xbox Game Pass Ultimate and supports full cross-platform play between PC, Xbox, and PS5. An open beta on Steam will run from April 9-11 for those eager to try it.

5. Clean Up Earth

Launching on April 2, Clean Up Earth offers a different kind of co-op experience. This first-person nature restoration simulator tasks players with vacuuming plastic, recycling waste, and reviving polluted areas. As players clean up, they witness the environment healing in real time, with plants growing back and wildlife returning. The game supports up to 25 players in large shared maps or seven-player private sessions. What sets Clean Up Earth apart is its integration with real-world environmental initiatives, allowing players to contribute to donation-driven objectives without spending any additional money. With full crossplay across platforms, this game is ideal for eco-conscious players seeking a laid-back multiplayer experience.

6. Diablo IV: Lord of Hatred Expansion

The latest expansion for Diablo IV, Lord of Hatred, introduces significant updates to the enduring dark fantasy franchise. This expansion takes players to the islands of Skovos, where they confront Mephisto’s growing influence. Seamless 4-player co-op gameplay remains intact, alongside newer tools like a party finder and AI mercenaries to ensure no one faces the fight alone. Key features include War Plans, which allow groups to customize sessions by chaining activities and tailoring rewards, and new horde and mechanic-driven modes. The expansion also adds two classes: the tank-support Paladin and the control-oriented Warlock. Both aim to enrich group teamwork dynamics. Returning fan-favorite mechanics, like the Horadric Cube, sweeten the deal for long-time enthusiasts.

7. Pokémon Champions

As a battle-centric spin-off, Pokémon Champions strips away exploration and focuses solely on competitive battles. Available on the Nintendo Switch Two starting in April, it supports global matchmaking for ranked battles, casual modes, and private lobbies where friends can test their skills. Players can import Pokémon from other games (via Pokémon HOME) or use loaned ones. Despite its free-to-start billing, many features, such as importing Pokémon and premium battle passes, require payment. This title is significant for competitive players, as it will serve as the official platform for the 2026 Pokémon World Championships. Expect refined mechanics, including Mega Evolutions and exclusive new moves.
