Dedicated Mars Base generator with 6 segment types (entry, shaft, corridor, turret hall, hive, arena), depth-scaled difficulty, and exit to boss arena after 2 generated levels. Mars themes integrated into all 7 generic segment generators. Full level chain: moon03 → mars01 → mars02 → mars_base (×2) → mars03 → station. Also: jetpack fuel pickup preserves recharge progress, depth counters reset on game loop, NULL checks on entity spawns, charger charge timeout, bg decoration in Mars Base generator.
