Simpley put, we need a co-op.
The two players share money, units, and share 1 brain.
When cycling from unit to unit, if a unit is controlled by the other player, it has some sort of sign above it, to know that unit is already controlled.
Friendly fire? That could be an option, yes or no.

WE NEED CO-OP!

Friendly fire would have to be on, in my opinion.

I JUST HAD THIS IDEA LIKE 20 MINUTES AGO! YOU STOLE IT!

But yeah. It would be great. And also online play.

ff already exists, just walk into each other and you both explode...

That needs fixing by the way

I realize that, lol. I just meant that in my opinion it would go completely against the game's design philosophy to not have friendly fire.

I completely agree with the friendly fire being on deal, with all the phyics, and crashing rockets and the like, it'd have to be a nessesitity, I was just saying maybe, to appeal to a wider demographic. <_<

I agree with the co-op.

I agree with shaving a cat bald and dipping it in tar to then stick to a bull named henry

Well, at least co-op wouldn't be hard. Getting it on a network would be difficult, however, and it's always difficult to play on the same comp (well, without gamepads, anyway). Certainly would be nice, but it would just increase the clamoring for network capability, and the last thing any dev needs is everyone pressuring him to do something that probably wouldn't work anyway.

Me and my brother play on the same keyboard fine...

Man, I'm getting tired of people whining about how we need to implement a mouse aiming system.
What'll happen when you play on the same computer? Shove a mouse in the slot that doesnt exsist? -_-

Who the hell needs mouse aiming?

The system is great as is, even my brother who has Autism can play with the current system... And hes got the intelligence of someone half his age.
Hes 14 if you want to know...

I'd like network a whole lot more then co-op, maybe co-op on network?

I'd backstab yah'.

Isn't there a minor problem with the fact that Windows only recognises three or fewer pushed keys at the same time (or something like that)? I seem to notice that when I'm doing multiplayer with my friend, he hogs all the keys so I can't do anything. Jetpack AND fly right AND shoot do not need to all be used at the same time, PAUL!
