Unit 7 · Global Conflict · c. 1900 – present
Front Line: Checkpoint Advance
Drive a tank across the battlefields of the world wars: the mud of the Western Front, the deserts of North Africa, and the snows of the Eastern Front. Every few seconds a checkpoint question appears at the top of the screen and a gate of three answer banners rises over the road, switch into the lane with the right answer. Right answers earn power-ups; wrong ones cost a strike and show you the real answer.
Switch lanes← →hop one lane per press (A/D, or swipe/tap on touch). SPACEstart, or pause during a run. The tank drives itself and picks up speed the longer you last.
Pick your laneRead the question, then be in the left, middle, or right lane as you pass the gate.
Dodge & collectSteer around barbed wire, tank traps, and parked supply trucks, and the odd truck driving ahead of you; grab trails of medals as they hop lanes. Pickups: shield, ×2, coin magnet, and the uncommon airship lift (10s carried over the battlefield: no hazards, no gates). Correct answers also earn a power-up; three in a row = a guaranteed shield.
3 strikes · 2 bumpsA wrong gate costs a strike (−1 ♥); lose all three and you have to retreat. Hitting something slows you down and leaves the tank damaged for 10s, hit another while damaged and you're knocked out.
Tip: click the game first so the arrow keys switch lanes instead of scrolling the page.
