As a long-time fan of the original HKAT, I've been after a good Hong Kong gun-play game for a while.
Now, while Full Clip fits the bill and serves well I should add that it is only focussed on heroic bloodshed/gun-play scenarios. There's nothing here for kung-fu, weird fantasy or other HK genre, though it likely wouldn't be too hard to develop these.
The 1PG system is very simple, but I'd say requires a competent GM to really run. It can be deadly, but this isn't a bad thing really, as the movies it replicates are oft' deadly too.
So overall, it looks nice, with solid presentation and style. If you're familiar with 1PG or just rules-light games in general, this might work well for you.
