Showing comments on Archive page

I’ve been trying to modify the archive.php to show comments by default on the archive listings page that I can get to by clicking through a category link.

Default setting for WP is to just show the post title and the text without showing the comments, then loop the function to display the next post in the chronological order. Comments can only be viewed once you click through the link that displays how many comments have been submitted for that post.

Has anyone achieved this?
