Marathon Implants Guide: The Complete Cybernetic Database
Getting dropped into Tau Ceti without knowing your stat penalties is a guaranteed way to lose your entire loadout.
Marathon is an unforgiving meat grinder of an extraction shooter. You are going to die frequently. If you want to survive longer than five minutes against UESC commanders and rival crews, you need to understand your physical shell. Implants are the passive buffs keeping you alive, but they are absolutely riddled with nasty tradeoffs. A shiny new bionic leg might make you sprint faster, but it could completely tank your ability to heal mid firefight. If you are brand new to this brutal loop, I strongly suggest reading my Marathon beginners guide before you even think about messing with your cybernetics.
Your Runner rig has exactly four slots for these hardware upgrades: Head, Torso, Legs, and Shield. The Shield slot is incredibly easy to miss when you first boot up the game, but it completely dictates your survivability.
Understanding The Stat Tradeoffs
Before we get into the massive catalog of hardware, you need to understand the stats you are actually modifying. There are 13 core stats in the game. Some dictate your movement like Agility and Heat Capacity. Others manage your cooldowns like Prime Recovery and Tactical Recovery.
The biggest trap new players fall into is ignoring the negative numbers. A high tier implant will often nuke your Hardware stat (which dictates how long physical status effects stick to you) or your Self-Repair Speed. If you tank your repair speed, your healing items take an eternity to apply. You can mitigate this by memorizing my all consumables explained guide, but you are better off just building a balanced rig. Similarly, if an implant lowers your weapon handling, you better be running something from the top of the best weapons tier list to compensate.
Implants come in five rarity tiers ranging from Standard all the way to Prestige. Prestige items are the holy grail because they grant Unique Traits, which are massive gameplay modifiers. You can find these in Bioprinter caches out in the world or buy them from vendors. If you need cash to buy them outright, check out my factions guide to optimize your contract payouts.
The Head Slot Inventory
Head implants lean heavily into utility, scanning, and recovery metrics. If you are playing the dedicated medic or scout for your crew, this is where you make your money.
The Torso Slot Inventory
The Torso slot contains the widest variety of buffs in the entire game. You can build out for raw melee damage, extreme looting speed, or pure survival. Holy shit, the V5 Nimble Fingers will save you so much time clearing zones if you manage to extract with it.
The Legs Slot Inventory
Your lower chassis dictates how fast you move and how much heat you generate while sprinting. Getting caught in the open with an overheated rig usually ends with a sniper round through the visor. Optimize your heat capacity.
The Shield Slot Inventory
Do not ignore this slot. Modifying your base shielding fundamentally changes your time to kill in a PvP engagement. Dropping your Prime Recovery to gain reinforced shields is a massive tradeoff but entirely worth it for aggressive players.
You will inevitably spend hours grinding XP and risking your neck for a Prestige tier implant only to get sniped at extraction. Welcome to Tau Ceti. My best advice is to not hoard your mid tier implants in your stash. If you need a fast track to leveling your character so you can survive these high stakes drops, review my how to level up fast guide. Slot the best gear you have on every run, read the stat penalties carefully, and stop complaining when a compromised implant breaks on exfil.
