What's Different?

This guide is solely intended as a "changelog" for players who already have experience with other SS13 servers centered around humans fighting Xenomorphs. If you're new to this sub-genre, check Handbook to Merc. If you're new to SS13 entirely, you're pretty much on your own for now.

Universal Changes
- The average human is now more powerful than the average Xeno. This is due to a massive balance change listed below. On this server, Xenos are closer to a zombie horde than intelligent murderous parasites with impractical reproduction.

- Rounds are extremely fast paced, with the action starting ten minutes after roundstart, and usually ending within twenty to thirty minutes.

- Roleplay is not required, nor enforced.

- Z-Levels are fully integrated. Mercs can fire down from rooftops, and flying Zurganids can try to attack Mercenary bombers. Press the F key to look up or down.

- Movement is pixel-precise, not tile-precise.

- Running into an enemy will automatically hit them with the strongest melee weapon you have in your hands.

- A universal ammunition system is utilized, weapons and item pouches are refilled using Morphic Industrial Compound.

Mercenary Gameplay
- The main faction are the MercDonald's Mercenaries. Marines are a separate(and hostile) faction.

- There is no friendly fire. Including Orbital Bombardments. The only exceptions are landing vehicles and barbed wire. This is also a consequence of the extreme balance change further down.

- Each squad has their own pod to deploy to the mission area, which have their landing zones picked by the Squad Leader or Overwatch officer.

- Squads have specific mechanical roles. Alpha is the entire normal ground force, Beta has jetpacks to flank Zurganids or guard the smaller shuttles, Gamma is the mechanized squad with slow but stun-immune power armor, and Delta is a squad of Specialists, albeit with less extreme gear.

- Medicine is extremely simplified; there are only three damage types. Brute, which governs all physical trauma. Burn damage was combined with brute damage. Toxins, which occurs when Stamina is depleted(usually occurs when in critical condition and out of Stamina) or hazardous gases like Plasma are inhaled. Stamina, not necessarily a damage type, but running out of Stamina causes toxins damage. Stamina can be depleted by over-using abilities, or going into critical condition.

- The only shipside role is Crewmen, who handle engineering and supply tasks on board a support. All other jobs that you might expect are taken by more Screeches, which are not player-controlled.

- ALL combat equipment, including attachments, are acquired at the same equipment machine, and every role is given a separate weapon and gear budget depending on their job description. Armor is chosen first, and can determine what gear is available to you.

- Mercenaries win via completing objectives, instead of just killing their opposition.

In Extermination missions, Mercenaries will have the objectives of finding and rescuing Ronald, a special Screech hidden in a Vault somewhere within the colony, securing artifact containers, also found within the same vaults, and retrieving resin cores dropped by dead Zurganids. Once the Extermination order is unlocked after the required amount of goal points being fulfilled, the Mercenaries will need to defend the Ship for ten minutes.

In raid mode, in which alot of extermination's gameplay is inherited, the ship phase is skipped in favour of a simple evacuation phase that begins once the mercenaries have completed their goals, or once the mercenaries have taken too many losses.

- Completing objectives gives goal points, which are required for victories.

- Skills have been simplified into a MERCS score, detailed at MERCS and You. Importantly, they only impact efficiency; any Mercenary can use anything, but they might need someone else's ID to do so.

- All Mercenaries are immune to overdoses and facehuggers. Excess reagents will be purged, and facehuggers temporarily blind a Mercenary, and infect Screeches.

Zurganid Changes
- Xenomorphs are Zurganids in here, and will be referenced as such in this wiki.

- Zurganids respawn infinitely. They drop Resin Cores important to the Mercenary faction when they die, and respawn at deployed Hive Zurganids, which are the only caste that cannot respawn, or the Queen, who can. Any dead player may join the Zurganids at will, provided there are enough slots. This is the reason for both bolded points above.

- The Queen has lost her stuns in exchange for becoming a mobile spawn point; she also has the ability to summon the ENTIRE Zurganid team to her location on an extremely long cooldown. In a pinch she can spam facehuggers, but they won't do more than blind the Mercenaries. Her death drops a more valuable Resin Core, instead of crippling the hive like you may expect.

- Zurganids can eat dead Mercenaries to contribute to the hive's overall strength level. More important roles count for more biomass.

- There are only eight body types, including the unique Queen and non-respawning Hive. There is also no tiering system; Zurganids can individually upgrade their stats in one of four places as the hive gains more biomass.

Refer to Zurganids for more detailed information on the faction.
