Cons
Con Bad visual design
Obviously this is an open soruce project so nobody expects AAA level gfx but this one looks exceptionaly bad. Some of the weapon effects are hideous to look at. Simple things like UI buttons and color scheme seem to be visually out of sync with the way unit models and the map terrrain look.
It seems like a mishmash of visual styles which is probably a result of many different contributors of varreying skill levels.
There definately are visually consistent and pelasant ot look at open source games so The visual design of the game needs to have some sort of strcut guidline or rely primarily on the taste of a single individual from the ZK team.
Con Flat balance
The economy is very close to a Total Annihilation economy (despite all the changes they introduced) but the unit balance resembles games with harder unit counters like Warcraft and Starcraft. In Blizard games, there are different ways to limit what unit type or kind you can build at any stage of the game, like tech structures which the opponnet can scout.
In Zero - K this is not the case since there are no tech buildigns focusing the player on a certain unit type which can be scouted. You can make all units at all times. The gameplay design feels amateur and not thought through From the broadest perspective. It also manages to miss the advantages of the Spring engine and mixes the need to micromanage units that counter each other with big Area of Effect Weapons.
Con Can be complicated to play for a beginner
For those unfamiliar with this style of game, there is a lot to learn in order to be competent at the gameplay. Some tutorials online should help, but it is a time investment some may not want to spend on the game.
Con Micromanagement is a bit too much
You have to either use glitches or really make all your decisions right.
Con Can be boring when playing alone
Due to the length of the win conditions and how long it takes to achieve things in the game, it can get a bit boring after much time spent. This is also true of the stock gameplay element, while mods can definitely help, what comes with the game out of the box can get old after a while.
Con Graphics are small on high res displays
When playing this game on a high resolution screen the game will look small and dense, which may be irritating that it does not scale to ones resolution as it can be difficult to read the text or see what is going on. However, in the settings one can set the UI scaling to 2x to make it much easier to tell what is going on.
Con The sounds drive you insane
You sit down to play the game for a slight bit of time, you get your headphones on and get blasted with BEEEEP and GJHHHH including VSHHH and DING DING DING DING WOOOSHHH too.
Con Online does not work cross versions
Old versions can't play online or LAN with newer versions of the game. So for those that prefer using an older version, or just have not updated, they will have to make sure those they want to play with online have the exact same version (or one that is compatible).
