Swarm Survivor: Endless Siege

Swarm Survivor: Endless Siege is a sci-fi bullet-hell roguelike where you repel waves of alien warships using automated combat that emphasizes pre-battle strategy. Rather than twitch aiming, you configure and tune a defensive loadout and unlock passive talents between runs; a standard 30-wave campaign leads into an Endless Mode for score-chasing, while random events and persistent progression force adaptation and encourage experimentation with synergies. The game is built around planning and buildcraft instead of direct control, rewarding players who enjoy strategic preparation and discovery of combinations. A playable demo is available and the full release date has not been announced.

Swarm Desktop

Swarm Desktop is a free application that simplifies running and overseeing Swarm nodes for participation in a decentralized storage layer. It’s aimed at both newcomers and experienced operators who prefer a clear graphical interface over the command line, and provides simplified node setup, live status and usage statistics, built-in log viewing and troubleshooting features, and easy configuration of storage and networking options. By streamlining routine tasks required to contribute capacity—setting up a node, monitoring its health, and adjusting settings as needs change—it lowers the barrier to entry and encourages reliable participation in the network. Alternatives include command-line tools for users who prefer terminal control and other GUI utilities for inspecting stored content.

Night Swarm

Night Swarm is a paid action roguelike that blends bullet‑hell combat with survivors‑style runs, putting you in the role of a young vampire lord trying to reclaim power. During short, intense runs you summon and command minions, face waves of enemies and bosses, spend gold at risky totems for powerful rewards, and swap or buy abilities and items; between runs a castle hub lets you recruit followers, buy permanent talents, unlock equipment, and manage progression so each attempt contributes to longer‑term growth. The game’s strengths are its vampire-centered twist on the formula and tight, challenging combat that rewards build choices and reflexes. Drawbacks include a grindy resource loop that can feel repetitive and elevated expectations for polish and content given its premium price.

Funguys Swarm

Funguys Swarm is a cartoonish action roguelite where mushroom heroes try to save a forest from a spreading fire. Runs are fast-paced and chaotic, featuring mutated vegetable enemies, bizarre weapons and tools fashioned from forest materials, outrageous abilities and over-the-top attacks that let you chain dramatic moments, and tight bullet-dodging combat that rewards improvisation. You gather upgrades, adapt your build on the fly, and combine weapons, pets, skills and power-ups to create unexpected synergies while facing boss encounters that test those combos. Progression unlocks new skills, passive bonuses, pets and late-game toys that reshape how runs play out, and a small pool of unlockables encourages experimentation and replay. This is best for players who enjoy hectic, arcade‑style survivals that reward creativity, a lighthearted tone rather than grim realism, and roguelite progression with bullet‑hell mechanics and whimsical visuals.

Alien Rage - Unlimited

Alien Rage - Unlimited is a sci-fi first-person shooter set in an abandoned asteroid mining facility overrun by hostile extraterrestrials. The action is fast, arcade-like, and focused on clearing waves of enemies through corridors and open areas while scavenging for better gear. You unlock upgrades that boost survivability and logistics, and the arsenal mixes human and alien weapons that you can swap as you find them, with limits on how much heavy firepower you can carry. Combat is brisk and satisfying with a steady flow of encounters, though the mechanics and level design closely follow established shooter conventions. For a different take on alien-blasting action, consider Alien Shooter 2.

Alien Shooter 2

Alien Shooter 2 (Alien Shooter: Vengeance) is a top-down action shooter developed by Sigma Team. Set in 2030, players are sent into an overrun corporate facility to eliminate an infestation, extract survivors, and secure sensitive data, with branching choices and NPC encounters that affect outcomes. The game blends arcade run-and-gun combat with light RPG progression: a large variety of firearms, support gadgets, vehicles for crowd control, and unlockable abilities and upgrades let players customize tactics. Modes include a story-driven campaign, survival runs, and cooperative multiplayer, all designed around massive, relentless enemy hordes and fast, visceral encounters amplified by environmental and audio effects. The focus is on high-adrenaline combat, continual progression, and replayability for players who enjoy intense, nonstop action.

Steel Swarm: APOCALYPSE

Steel Swarm: APOCALYPSE is a high-intensity strategic MOBA that puts you in control of heavily armed Xalium battle tanks in the collapsing city of Rotnor. Matches feature three lanes swamped by dense, fast-moving minions, while players select a tank and pilot and balance mobility, aiming and positioning as weapons are fired on the move. The battlefield is highly destructible, letting you blast walls and foliage to open shortcuts, create flanking routes or carve escape corridors. Several factions contest the city and neutral groups provide side objectives, creating shifting tactical opportunities across the map. Progression unlocks tiered upgrades that let you tailor mobility, armor and weapon systems, and success hinges on coordination, situational awareness and rapid decision-making—choosing when to push lanes, take objectives or hunt high-value targets. The game emphasizes cinematic, large-scale clashes where map manipulation, vehicle customization and synchronized team play determine victory.
