Into The Abyss - Abyssal Deadspace

Mutaplasmids dropped 2018-05-29 and instantly rewired high-end PvP fits - modules now have rolled stat ranges, so the "best" faction module is no longer a static stat-stick but a market hunt for a good roll on web range, scram strength, etc.

Entropic Disintegrators arrived as the first "ramp-up" weapon system in EVE - damage builds over time on a single target up to ~50% above initial, no falloff but a hard optimal, fundamentally different fit logic than turrets/missiles.

First Triglavian PvP hulls (T1 Damavik / Vedmak / Leshak / Drekavac) added a cap-warfare-vulnerable, web-friendly hull line; the entosis-link fits and the early Vedmak gangs were the visible meta change in low/null small gang.

Abyssal Proving Grounds: 1v1 / 2v2 / 3v3 limited-fit arena PvP became a recurring weekend mode, the first sanctioned "arena" content in EVE - gave duel-PvP enthusiasts a permanent home.

T2 ammunition was unlocked for use with Faction / Storyline / Officer weapon variations across all sizes - opens up Officer-gun + T2-ammo fits that were previously gated.

Abyssal Deadspace launched as a brand-new content type - solo (and later 1-3 ship) procedurally-generated PvE rooms reachable from anywhere in the game via Abyssal Filaments, with 5 difficulty tiers and a hard 20-minute timer that destroys your ship and capsule on failure.

Abyssal pockets carry environmental effects - Dark Matter Field, Plasma Firestorm, Exotic Particle Storm, Electrical Storm, Gamma-Ray Afterglow - that flip resistance/range/recharge bonuses, so you fit per-environment (and the rolled tier on the filament tells you which).

Triglavian, Drifter, and Sleeper NPCs appear inside Abyss rooms with novel mechanics - neut towers, web towers, energy-vampire frigates - pushing PvE skill demands well above the L4-mission baseline of the prior decade.

The Agency PvE finder was rebuilt to surface available content (anomalies, missions, abyssal filaments, events) at a glance - the on-ramp for returning players looking for "what should I run tonight".

Mutaplasmid-rolled tank/booster modules became the natural progression target for PvE pilots running cruiser/destroyer Abyssal - a returning-player ISK sink and skill ceiling at the same time.

Abyssal Filaments became loot - they drop from anomalies, sites, and certain hulls, so your scanner is now hunting for filament drops alongside relic/data cans, with T4/T5 filaments commanding strong markets.

Triglavian-themed exploration sites and bioadaptive datacore loot pre-seeded the Triglavian invasion arc that would go live a year later - explorers got "in on the lore" before the wider playerbase.

Abyssal Deadspace itself is a kind of explorer content - randomised rooms, environmental effects, no two runs identical - pulling exploration-temperament players into PvE that previously felt repetitive.
