Save anywhere, resume anywhere. A new Save & Quit on the pause menu captures the exact state of your run — wave, towers, supplies, every structure — and Continue on the main menu drops you straight back in. No more losing a session because you needed to step away.
Named manual saves. Save and Load buttons on the pause menu keep titled slots between runs, handy for testing different builds against the same wave.
Replay any wave. From the pause menu or end-of-night summary, jump back to any wave you've completed in the current run and try it again. Replays are deterministic — same seed, same sequence — so you're comparing decisions, not RNG.
Playtest fixes (0.54.1 – 0.54.3). The early kinks ironed out: the Replay Wave dropdown now populates correctly on AMD GPUs, walls and the FOB no longer leave slight-offset duplicates after a replay, and a sizeable chunk of background error noise has been silenced.
