Agent 64: Spies Never Die Guides
Fast Leveling in Agent 64: Spies Never Die
There are no checkpoints or mid-mission healing -- going down means restarting from the beginning. Treat early attempts at any mission as reconnaissance: learn enemy placement and objective locations on a "doomed" run rather than expecting to clear it clean the first time.
Beating a mission's par time unlocks Paradox Mode content -- if you're aiming for these, prioritize a clean, fast, low-risk route through a mission over full exploration, since speed is being directly measured and rewarded here.
