Save The Flag (AppID: 3878320)

Save The Flag is an intense, arcade-style single-player shooter where you stand alone against a relentless horde of zombies and monsters. Your only mission: protect the American flag at all costs. Armed with a powerful arsenal and a trusty jetpack, you'll face procedurally mixed levels full of danger and action.

Each run consists of three stages, blending handcrafted level design with random elements to keep things fresh. As you battle through waves of enemies, every kill earns you points – and the longer you survive, the higher your score. You can unlock and maintain persistent score multipliers, and occasionally, glowing bonus zones will appear where kills count double. The chase for the highscore becomes not just a reflex challenge, but a tactical game of risk and reward.

Between stages, you’ll be given powerful upgrades that shape your run. Choose from game-changing perks like the explosive Rocket Sniper or a passive Damage Aura that fries enemies around you. Your weapons—ranging from ninja sword to sniper rifle, M4, and grenade launcher—can be leveled up mid-run, unlocking more damage and new effects.

At certain points in the game, a portal will be unlocked somewhere in the level, allowing you to advance to the next stage—if you're ready for it. Be warned: with every stage, the difficulty increases. But so do the rewards.

While Save The Flag might look like pure chaos at first glance, reaching the top of the leaderboard requires sharp reflexes, clever upgrades, and knowing when to hold your ground—or take the portal and risk it all.

Built from scratch by one person with way too many ideas, not enough QA testers, and a whole lot of help from Unreal Engine and Epic.

Thanks for playing – now go defend that flag!

Oh, and did I mention the grenade launcher with an adjustable detonation timer? Yeah... you're welcome. 😏
