Cons
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).
Con Can get a bit repetitive
The gameplay doesn't change much from mission to mission; you’re generally just shooting aliens over and over again.
Con Gameplay is too short
The main story only takes about three or four hours to complete, which means you could beat the game in one sitting pretty easily.
