Demon KillerDemon Killer is an intense, top-down arcade shooter where you stand as humanity's last defense against a demonic invasion. This browser-based action game challenges you to survive relentless waves of monsters using an ever-growing arsenal of weapons. With simple mouse and keyboard controls, you'll navigate horror-filled arenas, gunning down creatures in a frantic fight for survival.
In Demon Killer, your primary objective is to survive for as long as possible against an endless horde of demons. You'll move your character around a confined map, aiming with your mouse and shooting with a click. Defeated enemies drop experience points and sometimes special power-ups.
As you collect experience, you'll level up, which often presents you with a choice of powerful temporary upgrades for that run. This rogue-lite element means every game is different, as you adapt your strategy based on the upgrades you're offered, from multi-shot projectiles to increased movement speed.
You aren't fighting these monsters with your bare hands. Demon Killer features a wide variety of firearms to help you cleanse the world of evil. You'll start with a basic pistol, but you can soon acquire shotguns, machine guns, and even more exotic weaponry.
Each weapon has distinct advantages. A shotgun is perfect for clearing out a dense cluster of enemies up close, while a machine gun can lay down a continuous stream of fire to control choke points. Managing your ammo and knowing which gun to use for each situation is key to achieving a high score.
The game throws a diverse cast of monsters at you, each with unique behaviors. You'll face small, fast-moving imps that try to swarm you, as well as larger, tank-like brutes that absorb a ton of damage. Some demons even have ranged attacks, forcing you to constantly stay on the move and prioritize your targets carefully.
You can play Demon Killer directly in your web browser with no downloads or installation required. Because it's a free HTML5 game, it runs on most modern devices and can be accessed on networks at school or work, letting you jump straight into the action whenever you need a break.
Your goal in Demon Killer is to survive against endless waves of demonic creatures for as long as possible. The longer you survive and the more demons you eliminate, the higher your score will be. Control your character's movement using the WASD or arrow keys. The character will automatically aim at your mouse cursor's position on the screen. Use a left click to fire your equipped weapon. As you defeat monsters, they will drop experience orbs. Collect these to level up and gain powerful new abilities and upgrades for your current run. You may also find health packs or temporary power-ups to aid your survival. Between waves or runs, you can often use collected currency to unlock new weapons or purchase permanent upgrades, making you stronger for your next attempt to stop the invasion.
Stay Mobile - Never stand still. Constant movement is essential to dodge projectiles and avoid being surrounded by the horde. Prioritize Threats - Identify and eliminate the most dangerous demons first. Ranged attackers or fast-moving enemies should be your primary targets before they can overwhelm you. Know Your Weapon - Switch weapons based on the situation. Use a shotgun for close-range crowd control and an assault rifle for picking off enemies from a distance. Funnel Enemies - Use the level's layout to your advantage. Lead demons through narrow corridors or around obstacles to group them together for efficient takedowns. Upgrade Wisely - When you level up, choose upgrades that complement your current weapon and playstyle. A boost to reload speed is invaluable for a slow-firing shotgun.
