Verdict
Most tower-defence games send enemies down a path. Creeper World sends a flood. The Creeper is a liquid that pours from emitters, pools in valleys, climbs over ridges when it gets deep enough and eats anything it touches, and your job is to hold it back with mortars, cannons and terraforming until you can push to the emitters and cap them. It is unlike anything else in the genre, and the fourth game is the one where the idea finally has the 3D terrain, the pace and the campaign it deserved.
The Farsite Expedition story is light but well paced, and the real game is the Colonies browser, where several thousand player-made maps sit sorted by rating and difficulty, each one a new puzzle in how to read the flow. A one-person studio has kept the whole thing patched for five years.

Towers 17 of 20
Cannons, mortars, snipers, sprayers, berthas and nullifiers, plus the terraforming and energy tools that are really the point. There are fewer towers than in Bloons, but each works against a physical liquid rather than a hit-point bar, so placement on a slope matters more than the tower itself. A mid-game lull before the big guns arrive is the only soft spot.
Lanes 18 of 20
Terrain is the whole game. Height is defence, valleys are traps, and you can dig and raise ground yourself. The campaign maps teach this in a sensible order; player maps then take it to places the designer never planned.
Waves 17 of 20
The Creeper never stops and never cheats: it goes where gravity says. Pressure rises in a way you can see coming, and emitters, spores and the unit types in later missions each ask for a different answer. Losing is slow and informative rather than sudden.
Economy 16 of 20
An energy economy built on collectors and reactors, where every cannon shot costs power and overspending stalls your whole front. It is a real system that rewards planning, though it can be gamed by simply waiting on easier maps.
Longevity 19 of 20
Campaign, a Mark V sandbox and a Colonies browser with thousands of maps, plus Steam Workshop and online co-op. Five years of patches from a studio of one. If you take to the idea, this is a game for life.
