How Much RAM Does The Invasion Forge Server Need?
The Invasion runs TaCZ's firearms system and invasion-event mob AI on top of Forge 1.20.1, so RAM needs sit a bit above a plain zombie-survival pack — see the The Invasion pack page for the full feature rundown before you size your plan. Finnish players: Minecraft-palvelin hosting is our native-language page. German players: Minecraft-Server mieten covers the same hosting auf Deutsch. Svenska spelare: Hyra Minecraft-server täcker samma hosting på svenska.
4 GB
The bare minimum for a solo or two-player test session. TaCZ's weapon rendering and the invasion-event AI leave very little headroom, so expect stutter once zombie waves ramp up.
5 GB
The best starting point for most The Invasion servers — enough headroom for TaCZ's gun systems and the pack's invasion AI to run smoothly for a small group.
7 GB
Safer for a mid-size active group running regular invasion events, since more simultaneous zombies and gunfire both add load.
10 GB
For 10+ players or a long-running world, this keeps TaCZ's firearms and invasion AI stable even during the pack's biggest wave fights.
