The SS Revenant is an Epic Grade 4 Interceptor for players at Operations (and Shipyard) level 42+, with 15 tiers split into 3 evolutions -- one every 5 tiers. It's the first ship whose visual design actually changes through Refits after each evolution. It excels against hostiles and Armadas in Continuum Space (Amargosa, Nova Kron, Osbor, Corialis, Manmoor, and more), and is a best-in-class source for Grade 4-6 materials and resources.
Twice-daily Solo Armadas against Borg Type 03 variants and weekly Group Armadas against Borg Polygon variants both feed Continuum Refinery currency you exchange for materials, resources, and ship parts, plus Nexus Particles for research and Fabricator Chips for bulk refined materials. The Revenant also boosts damage and Chaos Module drops against existing Continuum hostiles (Assimilated Coryn-class, Frohmun-class, and Prohibitor-class). A side loop -- defeating Q Continuum hostiles for Chaos Modules -- funds Chaos Tech bundles and further ship upgrades.
Scrapping the Revenant at each milestone tier hands you a Refit that evolves the ship rather than destroying your progress: Mark II at Tier 5 (levels 21-25) adds 10 extra shots against Borg Type 03/Polygon Armadas and 500% cost efficiency on Revenant parts; Mark III at Tier 10 (46-50) adds 40,000 Apex Barrier and 5,500% cost efficiency against the same targets; Mark IV at Tier 15 (71-75) adds 42,000% cost efficiency. Each evolution also pays out large amounts of refined materials, Fabricator Chips, and Nexus Particles -- claimed from the Continuum Refinery after scrapping.
