Then select the icon under “File” and it will show you a list of processes running on your computer. When you have the game running, such as when you’re at the main menu, Alt-Tab back to your desktop and open Cheat Engine. The tutorial basically tells you how to discover cheats for a game, but I think it’s way easier to just search the web for a cheat table someone else created. That is your choice, but I found it confusing and definitely unnecessary. When you open it up the first time, it will ask if you want to go through the tutorial. If you want to cheat in the game like I did, download and install Cheat Engine.
I used this program for many other C&C games. I’m not too ashamed to cheat in some games, I actually think it makes the game much more fun and much less stressful for me. I did enjoy C&C4, but I used Cheat Engine to make me invincible, which may have altered my experience. Skip this if you’re not interested in cheating in the game: I decided to delete my “recommended” review for C&C4 on Steam, because I’m a bit mixed on whether or not I’d recommend it, so I thought I’d just share my thoughts on it here instead.
