Best Enemy Factions in Games You Love To Hate (Non-Villain Focus)

Many games feature powerful, organized groups – from huge alliances covering entire galaxies to secretive groups controlling small towns – that you’ll repeatedly fight against. These factions have distinct structures, specialized soldiers, unique weapons, and predictable strategies. Here are ten of these enemy organizations – not just individual bosses – that truly define their games through how they impact the world, the challenges they present, and how you approach each mission. They leave a lasting impression on everything from the environments you explore to the way you strategize.

The Combine

The Combine, first seen in the ‘Half-Life’ games, is a powerful, interdimensional empire that conquers planets. They use genetically-enhanced soldiers, security forces, and harsh resource gathering methods to control populations. In City 17, they maintain order through constant surveillance, energy barriers, and advanced technology like the massive Striders and Gunships. Players face enemies that combine human soldiers with robotic forces, demanding strategic use of cover, high ground, and focusing on the most dangerous threats. The Combine’s supply network – including central hubs, storage facilities, and railways – heavily influences the design of the game’s levels and key moments.

The Covenant

In the game ‘Halo’, the Covenant is a powerful alliance of alien races united by religious beliefs and organized into a rigid social hierarchy, ranging from the common Grunts and skilled Elites to the ruling Prophets. Battles with the Covenant emphasize teamwork, with Elites charging forward protected by shields and Jackals providing covering fire. Vehicles like Ghosts, Wraiths, and Banshees play a major role in combat, offering diverse tactical options. The Covenant’s plasma weapons and energy shields create a dynamic combat system where players must use careful aiming, grenades, and switching weapons to succeed.

The Locust Horde

In ‘Gears of War,’ players battle the Locust, a subterranean enemy that attacks from underground tunnels and heavily defended positions. The Locust army includes various types of enemies – from basic Drones and Kantus to powerful Boomers and Theron Guards – and massive creatures like Corpsers and Brumaks. They use clever tactics, like flanking maneuvers and keeping players pinned down, so you’ll need to move strategically between cover and work as a team. Whether you’re playing the campaign or the Horde mode, the Locust focus on wearing down their enemies and controlling the battlefield with explosives and powerful weapons.

The Necromorphs

‘Dead Space’ features terrifying enemies called Necromorphs – creatures brought back to life and horribly mutated by an alien force. Unlike most games where you aim for headshots, ‘Dead Space’ focuses on strategically cutting off limbs to defeat them. You’ll face different types of Necromorphs, from fast Slashers and hidden Lurkers to powerful, self-healing elites, all within the claustrophobic environments of spaceships and maintenance tunnels. The game uses sound and cleverly placed enemy spawns to build tension, and special abilities like stasis and kinesis are key to surviving encounters. The story and gameplay are tightly connected – the spread of the Necromorph infection directly impacts the dangers you face.

The Infected (Cordyceps)

In ‘The Last of Us,’ the infected aren’t just monsters – they represent different stages of a fungal infection, ranging from fast-moving Runners to heavily armored Bloaters. Each type has unique abilities and weaknesses. The game heavily emphasizes stealth and sound, as enemies like Clickers hunt using echolocation, and players can use distractions to their advantage. You can craft items like shivs and bombs, which are specifically useful against different enemy types and their detection methods. The game’s environments are designed to create tactical choices: do you sneak past enemies, fight in narrow spaces, or carefully manage groups?

ADVENT

In ‘XCOM 2’, ADVENT is the occupying force made up of humans working with aliens. They control cities by patrolling, scanning for threats, and setting time limits for objectives. When enemies come into view, combat starts, creating fast-paced turns where setting ambushes and attacking from the sides are key to success. ADVENT uses a variety of units – like basic troopers, stronger captains, armored MECs, and officers with psychic powers – that combine strong defenses, abilities to control crowds, and supportive buffs, forcing players to carefully build their own squads. Beyond battles, ADVENT constantly pressures players through strategic actions like launching counterattacks, triggering random events, and setting timers on important facilities.

The Reapers

In the ‘Mass Effect’ trilogy, the Reapers are intelligent, massive ships that can control organic life and create dangerous enemies called husks through local agents. Ground combat involves fighting different enemy types—like Cannibals, Marauders, and Banshees—who work together to exploit weaknesses in your defenses. Powerful combinations of biotic and tech abilities are crucial for breaking through the strong shields and defenses used by Reaper forces. The way you gather resources and complete important missions throughout the galaxy reflects the Reapers’ overall plan to systematically eliminate all life.

The Hive

In the game ‘Destiny’, the Hive are a civilization obsessed with death and structured with a strict ranking system – from basic creatures like Thrall to powerful Ogres and bosses linked to sacred locations. Combat against them often involves overcoming magical defenses, destroying enchanted objects, and stopping endless waves of enemies until you can complete your goals. Choosing the right weapons and abilities for challenges like Strikes and Raids depends on dealing the correct type of damage, overcoming enemy strengths, and having a high enough power level. The Hive’s unique buildings – made of chitin and filled with tombs – shape the battlegrounds and create different phases and challenges during fights.

Caesar’s Legion

In ‘Fallout: New Vegas’, Caesar’s Legion is a growing empire built on slavery, structured like ancient Roman armies. Their actions impact your relationships with other groups, how quests end, and who controls the area around the Colorado River. They favor close-combat weapons, sniper rifles, and are led by recognizable commanders, making them dangerous in medium-range fights and ambushes on roads and at bases. Your decisions will determine which of their camps you can access, what special equipment you can find, and ultimately, how the game’s political landscape is shaped.

The Helghast

The ‘Killzone’ games focus on the Helghast, a powerful and highly organized military society. They fight using well-trained soldiers, snipers, and armored vehicles in both city and arctic environments. Easily recognized by their distinctive visors and gas masks, the Helghast rely on coordinated teamwork, covering fire, and support from turrets and drones. Gameplay, both in the story campaign and multiplayer battles, emphasizes controlling key areas, mastering weapon recoil, and strategically moving between objectives – all reflecting their strict military approach. The game environments, like dust storms and cramped spaces, further support their preference for using cover and firing from multiple angles.
