Sector Grid

Sector Grid is a tower defense game featuring vision-cone targeting, randomized upgrades, and limited tower placement.  Across eight levels, you must utilize geometry, positioning, and puzzle-like decision-making to stay below the containment-leak threshold and clear each sector.

HOW TO PLAY

To place a tower, left-click a square marked with an arrow. Placing a tower costs 100 resources.

To upgrade a tower, right-click a tower and you will be presented with three random upgrades. You can upgrade each tower a maximum of three times. All upgrades cost 50 resources.

To sell a tower, right-click a tower and click the "sell tower" button. You will receive half of your total investment for the tower which includes resources spent on upgrades.

To beat a level, you must stay below the containment-leak threshold.

Available resources and the number of containment-leaks is listed at the top-left corner of the screen.

Beat all eight levels to complete the campaign. Each time you beat a level, you are given a score and your best score is saved. 

SCORING 

You are scored based on number of leaks and your total resources spent to beat the level. Number of leaks takes highest priority, meaning [0 leaks and 5000 resources spent] is better than [2 leaks and 1000 resources spent]. If the number of leaks is the same, then the lowest amount of resources spent will be the better score, meaning [3 leaks and 2000 resources spent] scores higher than [3 leaks and 4000 resources spent].
