A good first run is not about finding the perfect build. It is about learning which decisions keep the next thirty seconds manageable. These habits apply to Iron Core: Mech Survivor and to many action roguelikes with escalating waves.
The ten habits
1) Keep an escape route. 2) Read the safe-zone edge before chasing loot. 3) Upgrade the problem you have, not the build you planned. 4) Use defensive tools before the screen is already lost. 5) Do not split from your co-op partner without a reason.
6) Learn enemy movement before forcing damage. 7) Protect time as carefully as health. 8) Treat every run as a test. 9) Take a stable upgrade over a flashy one when pressure is high. 10) After a loss, name the first decision that made recovery difficult.
The first upgrade rule
Ask what currently ends your runs. If enemies reach you, improve space and control. If elites take too long, improve focused damage. If the safe area cuts off your route, prioritize mobility and map awareness. This question prevents a common roguelike trap: choosing upgrades because they are exciting rather than useful.
How to learn faster
Change one variable per run. Try a different defensive tool, route, or upgrade priority, then compare the result. Small experiments create a stronger mental model than copying a build before you understand why it works.

Frequently asked questions
What should beginners upgrade first?
There is no single best first upgrade. Choose the tool that addresses the immediate threat in your run, while keeping enough mobility and defensive options to reach the next safe area.
