Sorta, if you remove all the zombies, and instead put hackur players and/or newbs.
I'm sure that is a definite inspiration, but to compare the two with anything besides "zombie-game", would give warz too much credit.
Warz is more like a bush-running apocalypse simulator, where the good die first, and you never-ever-ever-never travel alone.
You remember the movie with Viggo Morteson the road? And that scene where he happens upon that group of bandits. Thats warz in a nutshell. TD plays the part of the bandits.
