Breachers will attack walls in their path indiscriminately, as opposed to sappers having a target.įor the mental state that makes these animals hostile, see Manhunter.Ī pack of scaria-infested animals have arrived, hunting for human flesh.

Breachers: Appears with breach-type raiders, such as tribals with breach axes or termite mechanoids.

Sappers: Sappers will try and mine or break walls to create the shortest route to a colonist's bedroom.

Smart: 'Unusually clever', will try and avoid traps and turrets.

Scatter drop: Raiders immediately attack via drop pod, which have gone 'haywire' and will disperse throughout the map.

Drop pods can go through constructed and thin rock roofs, but not overhead mountain. There is 40% to drop on an un roofed orbital trade beacon if one is present.

Center drop: Raiders immediately attack via drop pod, centered on one of your colonists.

They may assault the colony immediately, or stage for a time before launching their attack, giving you time to prepare.

Assaults: Arrive at the edge of the map, either by walking or by drop pod.

Tribal-level factions can't use drop pods, so are limited to assaults. Human raiders flee if enough of them have been downed or killed, or if enough damage to your colony has been done. Raiders will come and assault your colony, first attacking adult colonists that they can walk to, then animals and buildings. It is possible for multiple raids to happen at the same time, even of opposing factions. Each faction has defined raid compositions like the 'all sniper' or 'all melee attack'.Ĭommonly known as a raid, this event comes in several types. Once Rimworld has determined the faction, attack type and arrival type, a Raid Composition is selected. Some attack types only arrive via certain methods. Some arrival methods are not possible with some factions.

Some weights change based on raid points. After the attack type is chosen, arrival method is chosen. Some factions do not have all possible attack types. The weight of human factions can become 0 at extreme temperatures.Īfter the faction is chosen, the attack type is chosen. Mechanoids weight is 0 until 300 raid points. As Raid Points go up the weight of the Mechanoid Faction Increases. The mechanoid faction's weight changes with raid Points. Each faction is given a weight and all hostile factions are considered separately. Infestations and Mechanoid Droner, Defoliator and Clusters all required at least 400 Raid Points.Īfter the storyteller has chosen to fire a major threat, and chosen to fire a raid, first the Faction of the Raid is chosen. Some major threats are gated behind Raid Point amounts.

For example, Infestations and Mass Animal Insanity each require specific conditions that may not be met. Some major threats may not be possible at a specific time and would have a weight of 0. Each type of major threat has a specific weight. Special fired major threats are limited to Wastepack Infestations that can spawn when a wastepack deteriorates (Biotech DLC).įor Storyteller fired major threats, first the storyteller determines which type of major threat is to be sent. Quest major threats must be explicitly accepted by the player. Randy's 'schedule' is a random firing mechanic.

Storyteller major threats are fired according to the Storyteller's schedule. Major threats can be fired via 3 different methods: storyteller, quest, and special fired. Randy Random simply treats a major threat as an event that's less likely to happen. Their size depends on the raid points mechanic generally increasing in strength with wealth, colonist count, and difficulty.Ĭassandra Classic and Phoebe Chillax both treat major threats separately from other events they cycle between 'OnDays' and 'OffDays', where a certain amount of major events will occur during each OnDay cycle. They mostly consist of direct attacks to your colony. Major threats can appear from Base Builder difficulty onwards. 4.4.2 About: Getting advanced components.
