QUICK ANSWER
Survive each wave by preserving movement space, keeping a route out of a surround, and covering both groups and priority targets. Collect Keys and improve the loadout between runs, using only timings and costs visible in your game.
The official loop is clear even while exact wave timings, enemy tables and difficulty modifiers remain incomplete.

CONFIDENCE BOUNDARY
Final Swarm presents a direct loop: survive waves, collect Keys, unlock and upgrade weapons, build the best loadout you can, and progress through worlds. The order matters. A run produces observations and progression; progression changes the next loadout; the next loadout should answer the reason the previous run failed. That is more useful than copying an endgame-looking build without knowing which job each slot performs.
Area coverage stops dense groups from owning all nearby space. Range creates safer engagement options before enemies close in. Priority pressure removes the target that is forcing a bad route. Movement freedom keeps the player able to reposition while attacks recover or aim. One weapon can cover more than one job, but the planner makes overlaps and gaps visible using your own ratings.
Read the arena as a changing set of exits. Move before the nearest gap closes, not after every enemy is already in contact. Avoid backing into a corner for a small damage window. When the loadout has heavy movement burden, reserve more room and commit later. These are qualitative survival principles; they do not depend on an invented enemy speed or wave timer.
Recent YouTube results mention three difficulty modes, Nightmare challenges, a King Kong encounter and extended waves. Those titles show player interest, but a video title alone does not establish official labels, modifiers, rewards or timing. The updates page tracks these leads until direct gameplay observation or creator-owned notes support a precise table.
The official Roblox description says players survive waves, collect Keys, unlock and upgrade weapons, build a loadout and progress through worlds.
No creator-owned timing table was captured, so this page does not publish a universal duration.
Keep an exit path, move before the gap closes, use area coverage for groups, and avoid stacking too many high-burden weapons. The survival guide expands this checklist.
Recent videos use those phrases, but exact labels, modifiers and timing were not corroborated. They remain current gameplay leads, not confirmed tables.
