I've always rushed when I am in a vulnerable position, usually hides behind crates.
Because I know I'll be dead anyways, when people team on me. It takes three unskilled players to kill me usually and one skilled player to kill me usually, lol. but CS2D is really luck based and skilled based. None the less, it's based on your internet connection. If you have a really laggy modem for example... you'll get fragged. If you have a really godlike connection there's no way you can lose.
I think it also depends on what OS(
Operating system) your using too. I heard that Windows 98 versions are better to play CS2D on, rather than Vista. But it stays as a myth or a theory for now.
Here's my result, lol.
Old and slow computers increases vulnerability.
New and fast computers decreases vulnerability.
The internet connection is the thing that needs to get better. For better gameplay, you need more RAM aswell usually more than 256MB RAM is needed. You also need free disk space.
