3-2 MARS
3-2 Mars is the 2nd stage of Cosmos Ch.3 — Even Stars Burn Out. Previous stage: 3-1 Earth. Next stage: 3-3 Jupiter.
Hyppoh, Shibalien Elite, Star Peng and Helmut Krabbe are Alien. Anti-Alien units take less damage and deal more.
GROSS CAT A Its True Form is Strong Against Alien, giving budget anti-Alien value. 
LI'L GROSS CAT B True Form has a 30% Knockback vs Alien. 
WHEEL CAT A Deals Massive Damage to Alien enemies — a huge area nuke against Alien crowds and bosses. Also fits “Clear the crowd.” 
SURFER CAT A Area Freeze vs Alien controls Alien groups. Also fits “Clear the crowd.” 
CATMAN S Deals Massive Damage to Alien in every form. Also fits “Clear the crowd.” 6 enemy types stack up here. Area attackers hit the whole push at once instead of one unit at a time.
VALKYRIE CAT A Hits the whole group while it freezes them. WHEEL CAT A Hits every Alien in a wide area at once, melting grouped Star Aliens. Also fits “Counter Alien.” SURFER CAT A Area damage hits grouped enemies. Also fits “Counter Alien.” CATMAN S Long-range Area damage clears groups. Also fits “Counter Alien.” 
ACTRESS CAT B Hits multiple enemies at once for budget crowd damage. Star Pengs are the key threat — bring Warp-Immune cats and Anti-Alien Area Attackers.
Star Peng is back, Helmut Krabbe is back, Ginger Snache replaces base Snache. Same No Specials restriction. r/battlecats's read: 'Ch.3 Mars is the version where you finally appreciate having multiple Anti-Alien Ubers.' Mag scaling pushes Star Peng and Hyppoh into dangerous territory; Normal meatshields die faster than they did in Ch.1-2. Lineup: Normal Cat + Tank Cat + Wall Cat + Crazed equivalents (Crazed Cat, Crazed Tank — both Super Rare, legal under NO_SPECIAL) → Lumina, Bazibastra, Mighty Reza, Pixies for Warp Immunity + DPS. Common failure: bringing only one Anti-Alien Uber. The mag scaling means a single damage cat won't kill the Star Peng wave before it warps your line.
The castle you destroy to clear the stage.
