First off, I love how gun game is back. I also love the randomized weapon setups now. I absolutely hate that the combat knife can win the game though. It's way too easy to do that.
Once you get on that level it's game over. It's cool when everyone makes a gentleman's agreement to not use the combat knife at the end, but when one person wins like that it's really lame.
Just make it so the throwing knife needs to be the final kill and allow the combat knife to de-level. Man I'd even accept riotshield as the last weapon over combat knife.
