Aliens and Parasites Server Hosting

Aliens and Parasites is a 1.12.2 Forge pack built on two mods that each carry a whole game on their own. The AVP mod brings in the Alien and Predator franchises — facehuggers, drones, hives and queens, with xenomorphs that develop through stages rather than spawning fully formed. Scape and Run: Parasites adds a spreading infection whose creatures learn from fights and evolve as the world goes on.

Put together, they produce something unusual: a world that gets more dangerous the longer your server runs, regardless of how well geared you are. Most packs make you stronger over time. This one makes the world stronger too.

Scape and Run: Parasites is not a normal mob mod. It has phases, and it escalates. Parasites infect vanilla mobs and turn them into infected versions, they build up nests, and the mod tracks progress toward stronger tiers based on what happens in the world.

On a server that means neglect is punished. A group that leaves an infection alone for a few sessions comes back to something much worse than they left. The pack rewards active containment — finding nests, clearing them, and keeping the pressure down rather than letting it accumulate while everyone builds.

The pack runs on Minecraft 1.12.2 with Forge, which is where both of its core mods are most mature. It is a small pack by download count, so you will lean on the mods' own documentation rather than pack-specific guides — both AVP and Scape and Run are well documented in their own right.

Everyone needs the same pack build. Both mods add large numbers of custom entities, and a mismatched client will fail rather than degrade gracefully.

Plan for 5 to 6 GB even for a small group. The pack is not enormous by mod count, but it is entity-heavy by design, and entities are the expensive thing on a Minecraft server.

Expect load to rise over a server's lifetime as the infection spreads. This is the rare pack where a world that has been running for two months costs materially more to tick than the same world on day one, so leave yourself headroom rather than sizing for the first week.

• Create a Minecraft server and install the pack with its 1.12.2 Forge build.
• Let the first start finish, then check the console before inviting anyone.
• Give everyone the identical pack version.
• Look at the Scape and Run config before you get far in. Its evolution rate is the single most important setting on the server.
• Back up regularly. Infections can escalate faster than a group can respond.

The default parasite progression is tuned for a solo world. On a server with several players fighting things constantly, the mod escalates much faster than intended, and groups often find themselves facing late-phase parasites while still in iron gear. Lowering the rate at the start is far easier than trying to claw a server back once it has gone too far.

The servers that survive this pack treat the infection as a job rather than an event. One or two players scouting for nests and clearing them regularly keeps the world playable for everyone else. Groups where everybody builds and nobody patrols tend to reach a point where leaving the base is no longer possible.
