I'd like to request this hack, the only real thing I want is for the timer for the last mission to be off or put on infinite, something like that.
I don't want my units to be invincible or anything like that, but it will be a lot more fun if the timer is off. Thanks, -Brianf66

I've already hacked it myself, but you can still hack it and upload the hacked version yourself. Have fun~
