I used to play a LOT of CoD zombies during the Black Ops and Black Ops 2 days, also back when I had better FPS skills, lmao. Playing this was familiar, but the small details you added made a difference in my opinion. Like having to manually reload over an automatic action (more realistic and challenging), adding a fire mode selection is something usually blocked behind an "upgrade" when realistically most guns have that anyways, and the mag check and inspection are nice little details. I thoroughly enjoyed playing this as part of my Awesome Indies 2 video. I'll probably play more in my free time, and checkout UZG 2.
Thanks for making an awesome game! I love wave survival zombie games like this, but after Black Ops 2, I got out of CoD because things just started to turn into microtransactions and other BS. But this is zombies to its roots, and as I mentioned, big fan of the small weapons details you added. Keep up the awesome work! See if I can convince some friends to try out UZG 2 with me since it's multi-player, lol.
