Build lab
Worked examples for reloads, critical tiers, overnight upgrades and support connections in Deadly Days: Roadtrip.
Damage and upgrades
Reload time versus attack speed
Compare firing time, reload gaps and damage support before replacing a supported gun with Minigun or a faster weapon.

Critical chance above 100%
Calculate guaranteed critical tiers, the remaining chance and Astronaut’s current armor conversion without using old 100% caps.
Hammer upgrades: recipients, timing and rarity caps
Choose Hammer recipients before day end, account for its rarity ceiling, and preserve a working combat layout.

Boss preparation: Hank, Scoop, Dumpling and Mr. Kyde
Prepare dash windows, avoid damage terrain and keep attacks reaching bosses when ordinary map clearing stops being enough.
Unusual combinations
Crossbow, Battery and Walking Shoes build
Use Battery for on-hit lightning and Walking Shoes to trigger the Crossbow’s lodged bolts while moving.
Cogwheel, Throwing Knife and Tesla Coil build
Mark Throwing Knife and Tesla Coil with Cogwheel so their timed activations call the other attack once per chain.
Hand Mirror and Wi-Fi Repeater connections
Trace a support through Wi-Fi Repeater and Hand Mirror, preserve recipient eligibility and find the broken connection after a rearrangement.
Tesla Coil’s even-item rule
Count eligible electric items inside Tesla Coil’s marks, then recount after merging or moving one.
Secret Sauce and Food
Keep marked Food out of Secret Sauce’s selector, especially Special Banana and The Carver’s Grin.
