In each new season inOnce Human, players can choose between differentMemetic Specializationsto change how they build, craft, gather, or manage their territories. Four specializations arerandomly rolledevery five levels, andonly one specializationeach time can be chosen.Players can reroll specializationsa limited number of times per season, but will be provided different options the following season.
Depending on which Memetic Specializations are rolled, the player’s options for production will change, such as usingEnergy Links and Sulfur to produce Acidrather than using Polluted Water. Some Memetic Specializations may not be very useful to some players, some may always be convenient, and others are extremely valuable. Here are thetop 10 Memetic SpecializationsinOnce Human.

10Deluxe Storage Crate
More Storage For Late Game Materials
Storage Crates are extremely importantfor storing excess materialsyou need for crafting and building. Especially later in the season, Facility Spots become limited, withStorage Crates taking up one spot per crate. Instead, consider picking up theDeluxe Storage CrateMemetic Specialization, which allows players to now construct a larger Storage Crate with double the item slots. This way, you can reduce the total number of crates in your territory, and keep more materials in one small storage area.
A large Storage Crate with 64 item slots.
5/10/15
Not only are these useful for the player with the specialization, but they can alsobe built for other players, such as Hive members, if given building permissions to others' territories. Some players may even charge a small fee to do so, or propose a trade. Deluxe Storage Crates only take thesame amount of materialsas a regular large storage crate, making them very cheap to build.

Alwaysbe carefulgiving build permissions to other players! They will be able to buildand destroyobjects in your territory while the permissions are active. Be sure you trust the player and be prepared toremove their permissions quicklyafter services are provided.
9Super Refinery
Produce Fuel Faster
Super Refineriesare heavily desired by players withterritories located in oil fields, or dark areas of the map where oil can be gathered with Water Pumps. Unlike regular Refineries, Super Refineries need much less Portable Mixed Fuel to craft Barreled Premium Fuel. They are also able to convert Acid into Portable Mixed Fuel for further yield.
Transform Acid into Portable Mixed Fuel more Effieciently
These Super Refineriesoperate twice as fastto produce Portable Mixed Fuel and havetwo processing slots each, whereas regular Refineries canonly convert one material at a time. This means players can convert both Crude Oil and Acid into Portable Mixed Fuel at the same time, or can produce Portable Mixed Fuel and Barreled Premium Fuel.
Portable Mixed Fuel > Barreled Premium Fuel
Similar to the Deluxe Storage Crates, players can alsosell or trade servicesto buildSuper Refineriesfor other players.
8Backpack Expansion
More Carryweight For More Goodies
Backpack Expansionsare simple but valuable items that can increase your max load between 40-80lbs. These items can be crafted and have abase durability of 10 daysbefore they expire.
Backpack Expansion
Unlock New Formula: Backpack Expansion
When in your Backpack, increase Max Load by 40-80. Effect cannot stack.
While their effects cannot stack to grant you more Max Load, you can, however, sell Backpack Expansions in your Vending Machines to other players. Crafting and selling extras is a decent way to makeextra Energy Linksdepending on your server’s population.

7Sulfur Chemist
Convert Sulfur & Energy Links To Acid
Sulfur Chemistis an alternative way to produce Acid for those who do not havetheir territory in a polluted area. Instead of using the classic method of gathering Polluted Water with Water Pumps, players can instead use the Synthesis Bench in their territory toconvert Sulfur and Energy Links into Acid. If you have methods to gain additional Energy Links, such as thePrecious Metal RefiningMemetic Specialization, then this can be a viable way to produce Acid.
Slowly turn Acid into Sulfur using the Synthesis Bench.
20/25/30/35
Whileproducing Acid the regular wayhas many steps, this method only requires an open Synthesis Bench. Players have evenbuilt additional benchesto be able to produce more Acid at once.

6Electric Drill: Treasure Hunter
Double Your Precious Ore Harvests
TheTreasure Hunterformula improvement applies to both tiers of Electric Drills as well as Solar Drills crafted via theSolar DrillMemetic Specialization.
Electric Drill: Treasure Hunter
Improved Formula: Electric Drill
Enjoy +100% yield when mining for Gold Ore, Silver Ore, and Stardust Ore with an Electric Drill.
Using these drills grants players an additional +100% yield when harvesting Gold, Silver, and Stardust ore, which can then be refined into precious ingots using thePrecious Metal RefiningMemetic Specialization. Asbrewsterisaliveshows in the video above, Gold and Silver can easily befound in the Red Sands regionto farm.

World hoppingmakes this process even faster, as you can follow the farming route back to the Teleporter and then change worlds to refresh the route.
5Precious Metal Refining
Plenty Of Ingots For Energy Links
Obtaining thePrecious Metal Refiningspecialization now lets players smelt the precious ores they have harvested into Gold and Silver bars. Each bar can be sold for a high price to vendors in Strongholds, with Silver Ingots selling for 6,000 EL and Gold Ingots selling for 12,000 EL. This is one of the most viable ways to generate Energy Links for crafting, buying, and trading.
Precious Metal Refining
Unlock New Formula: Precious Metal Refining
Smelt Gold and Silver Ores into Ingots using the Electric Furnace. The Ingots can be sold for a large number of Energy Links.
Vendors in Strongholds can only purchaseup to 50,000 ELworth of materials per week. This means you may still have leftover Gold or Silver Ingots at the end of the week. If you have extra,try selling them in your Vending Machineat a reduced cost. Many players without the specialization will gladly purchase them to resell and generate a small profit.

4Solar Drill
Infinite Durability In Sunny Spots
Solar Drillsautomatically refill energy in sunny weather, which can be seen in the upper right-hand side of the screen.
Solar Drill
Unlock New Formula: Solar Drill
The Solar Drill charges itself on sunny days. Enjoy +15%-40% yields of Copper Ore, Tin Ore, Iron Ore, Aluminum Ore and Tungsten Ore.
When theweather icon is a sun, Solar Drills will regain charge and not lose charge while drilling. This is a huge improvement over regular drills,which will run out of chargeand break. Be very careful to monitor the “charge” of your Solar Drill though, asit can breakif you use it too much in cloudy weather without recharging!

3Generator: Electrical Expert
More Power = More Production
TheGenerator: Electrical ExpertMemetic Specialization is extremely useful for just about any player. It allows them to placeone additional generatorper territory and increases the output of each generator by anadditional +2W. Similar to other specializations, players can use this abilityat other players' territoriesto build them an additional generator.
Maximum Number of Generators +1, and +2w Power Output.

Depending on where your base is located, you may benefit more fromspecific generator Memetic Specializations. Examples would beHydraulic Generator: One With The Tidesfor players whose territory is on a river, orDeviant Power Generator: Stardust Unleashedfor those in a polluted area.
2Biomass Missile: Ample Munition
Triple The Missiles For Triple The Fun
For players participating in Prime Wars,Biomass Missile: Ample Munitionis irreplaceable. Biomass Missiles, which are ammunition required for Gatling Turrets, are needed to destroy the shields of Prime War bosses. With this specialization, players will be able to createthree times as many missilesfor the same amount of materials.
Plasma Missiles -80% Weight, and +2 Crafting Yield.
This specialization is inhigh demand, and players will frequently ask those with it tocraft Biomass Missiles for thembefore Prime Wars.
1Electric Furnace: Electrolysis
Double Your Aluminum & Tungsten Ingots
Electric Furnace: Electrolysisis the most valuable Memetic Specialization simply due to the high requirements for Aluminum and Tungsten Ingots towards the end of the season.
Electric Furnace: Electrolysis
Facility Boost: Electric Furnace
Doubles Yield when smelting Aluminum and Tungsten Ingots using the Electric Furnace.
40/45/50
Not only are they needed for building, but players will use hundreds if not thousands of ingots in orderto craft weapons, armor, and ammunition. Doubling the yield will provide a much-needed boost to supplies to limit the amount of grinding for materials.
Facility Boostspecializations will only be appliedafter building the facilityagain. Make sure tobreak down and rebuildany facility, such as the Electric Furnace, after you unlock the specialization.
Memetic Specializations reset every season inOnce Human, allowing players multiple chances to choose the ones they need for success. With cooperation between friends and Hive members, players can selectively choose specializations so that everyone benefits from their choices. Don’t stress if you don’t get the one you need! Even more underrated ones can still be useful depending on the player.
