Sorry for the late reply. There is a single player zombies mode but yes the other mode is online only. Once enough Money is gathered through donations, we will begin the creation of a second one with all your recommendations.
its just a zip folder, so download it and unzip it. then play it from there. There isnt a launcher for linux though, sorry. Just find the .exe for the game in the zip.
lol. I just checked in the file for mac and there are two files Spec Ops - Arrival Zombies.app and Spec Ops - Arrival.app. (Since i use windows i can go through the .app folder and everything looks right) My only sugestion is to re-download the .zip agin
yeah, on zombies, just click play and move around. There is a crawler on the fllor at the start of every game, so that is probably what killed you. Click controls on the pause menu if you dont know how to play. Also, yeah on zombies it is supposed to make you force quit. It kindof like a if you die, you die thing
