Start by targeting a single sentinel drone for basic escalation testing the alert mechanics carefully. Initial response brings standard drones which you'll want to deal with quickly to understand the timing, similar to how pieces need specific configurations to advance

Watch the propagation pattern closely cause each alert level follows strict rules. Combat drones show up first then those heavy hardframe quadrupedal mechs appear if you keep pushing it. Getting past basic alerts requires specific strategies just like solving those upward movement puzzles - maybe interesting to note that both systems have that layered progression thing going on

When maximum alert hits youve got to clear absolutely everything to reset the system back down. Proper timing matters here since elite units will keep spawning if you dont manage threats effectively. Tip: focus fire on standard units first before tackling the mechs, makes managing the waves much easier. Breaking line of sight temporarily can help reset positioning when things get too intense but remember the alert level stays active until you properly clear the wave

Really important to understand how the alerts stack cause once those elite reinforcements show up youre basically at the systems cap similar to hitting that fourth-row limit in the mathematical puzzle. Good news is defeating everything at max alert gives you a proper break from sentinel activity plus there's an icon that will appear on your hud that shows you how to shut down sentinel forces (resets after you leave the planet for some time)
