I remember from long time ago when I was still making maps I made a fortress in the middle of a big desert with AI coming from all sides throwing termite grenades at the player (was made with IC mod I believe). It had lots of random explosions (wooden bridges hidden below the ground make a nice bang, and so do oil tanks). It surely had lots of deaths the few times we tested it back then, I'm sure I must still have that map somewhere...
Update: Found all the good old maps on my portable HDD, including the IC mod Base Defence map Now all I need is to reinstall all mods and I could host it again for some madness match.
