Would be cool to be able to take over certain strong units by finding and infiltrating their home computersystems.
So you had the option to capture a unit directly with an engineer which is near impossible with big units or have their home server captured. Or have a machine/superweapon which disturbes the signal to the home server/commander. Home computer/server might also be an option to limit supply(if this makes the gameplay better, not sure)
Unit type: Nanobot package. Attack type: Capture. Dies upon success. Comment: Simpson's did it. er- I mean Blizzard.
My knee jerk reaction to any cyberwar thead is always "NO." But maybe this actually could be a cool mod. A special capture unit covertly captures an enemy engineer. That engineer then is returned to the original player's control, but is secretly controllable by the other player. It then goes on to infect, over time, other units within its "infection radius." This goes on and on until a sufficient number of enemy engineers are captured, which can then be suddenly turned on the player or self destructed. Or maybe your infectability (red underline? what? that's not a word?) could increase with each unit you've got captured, enabling you to covertly suicide a COM with dozens of zombie engineers. You'd need some ability to detect the attack, and this does sound like crazy micro management, but the idea is intriguing anyway.
This one's free I like the idea of guessing game type stuff. And stuff that allows you to attack your enemy's production. So what I'll propose is a unit that can hack into the enemy economy and steal a percentage of what he's getting. And an appropriate counter unit. Just like nukes this would be a game of risk vs reward, is the enemy investing into economy stealers? Is it worth it to invest in counter units? If I build one will it be effective, do they have counter units themselves? This is sort of a cyberwar type topic I think.
Economy stealer? Don't like that idea much, same as having to fully capture an enemy unit before being able to give it back. These methods are simply to obvious and no smart player should ever fall for them. If at all, then attach a wiretap to a unit and turn it into a spy thereby, but keep it unobtrusive. If you need to stop the enemy unit first, then it is useless as every attentive should notice that. It's fine if you are going to keep the unit (e.g. actual capture), but in every other case it should not be distinguishable from a regular shot or maybe even less noticeable.
