EVERY ICON IN THE GAME WAS REDRAWN. The 24 abilities, the 50 cards and the 19 Codex drawings got new art, four times bigger, and each one shows what the thing DOES: Vanguard became a lone warrior ringed by shapes, Crack became an armor plate with a glowing fissure, the Collector a little creature scooping gems. Along with it came an old fix: icons used to alias when the game drew them small, and now they shrink cleanly.
Fixes
THE ABILITY ICONS WERE TOO SMALL IN THEIR SQUARE. The new art had too much background around the drawing, and in the HUD's ability square it turned into a dark little smudge. All 24 were reframed by their core and now fill the space. The Codex icons had already gotten the same fix.
