Clue 1

Place value

We cracked the hijacked terminal's security lock by identifying the value of the digit in the thousands place on the server screen. This bypass revealed a secure file detailing the villain's tactical gear.

Clue 2

Addition

To unlock the supply bunker, we added up the total weight of the armored plates delivered to the front defense line. Inside the secure chest, we found a physical clue showing how the villain's gear is holstered.

Clue 3

Subtraction

By subtracting the fuel leaked during the getaway from the vehicle's maximum tank capacity, we calculated the escape route. Along the trail, we found a discarded report exposing the villain's system vulnerability.

Fractions of a number

The command center radar could only display a small fraction of the sector grid. Finding that exact fraction of active signal towers allowed us to locate a lost helmet component dropped by the fleeing suspect.

Clue 5

Fractions of a number — the last clue

Our scout drone scanned a fraction of the enemy base's radio frequencies. Finding that exact fraction of the total wavelength count gave us the final piece of data identifying the villain's headgear.

First solve each problem. Then find each answer in the list below and cross that sentence out. One sentence will be left — that's exactly what the villain did!

Step 1 — solve these
1/10 of 110 = ?
1/5 of 5 = ?
2/8 of 8 = ?
3/10 of 10 = ?
1/3 of 18 = ?
1/6 of 72 = ?
2/10 of 45 = ?
5/10 of 16 = ?
7/8 of 8 = ?
3/6 of 10 = ?
4/8 of 20 = ?
Step 2 — cross out the sentence with each answer
1.The villain blasted away in a recon jet, then blocked the base defenses with a shield generator.
2.The villain sped off on a hover bike, then blocked the base defenses with a shield generator.
3.The villain rumbled out in a heavy tank, then scaled the outer wall with a grapple hook.
4.The villain escaped inside an armored apc, then scaled the outer wall with a grapple hook.
5.The villain escaped inside an armored apc, then deployed a drone controller scout.
6.The villain zoomed off in a stealth heli, then deployed a drone controller scout.
7.The villain escaped inside an armored apc, then blocked the base defenses with a shield generator.
8.The villain sped off on a hover bike, then scaled the outer wall with a grapple hook.
9.The villain sped off on a hover bike, then disabled the local base grid with an emp grenade.
10.The villain rumbled out in a heavy tank, then blocked the base defenses with a shield generator.
11.The villain zoomed off in a stealth heli, then blasted the security lock using a laser rifle.
12.The villain zoomed off in a stealth heli, then disabled the local base grid with an emp grenade.
