Team Fortress 2 Gets Co-op Horde Mode

[Angrist]

I tried it but didn't like it. Uninstalled the game again.

Most games run fine... but I guess updating drivers and cleaning my HDD can't hurt.

I don't get the coop mode. It keeps saying I have to buy some tickets or I don't know what in a store. I didn't give it much time but it seems like I'd have to read a good while to get the hang of it. Has anyone played it yet?
