Most of the scenery is destructible, too, so you'll be able to wreck cars piece by piece or hurl your enemies face-first through plate-glass windows. A lot of what's lying around can also be picked up and used to crack skulls, whether it's an empty beer bottle, a wooden board or just a handy trash can. Given the PSP's track record for cutting features out of PS2 ports, it's impressive that all that stuff made it over intact.
It's also impressive that the handheld only occasionally chokes on all the onscreen action. See, The Warriors isn't a solitary brawler; you'll always have at least one computer-controlled Warrior (usually more) following you around, and you can tell them what to do by issuing simple orders. They come in handy when you're up against large groups of thugs, which happens pretty often, and the action only slowed down a couple of times when huge brawls erupted.
Even the two-player co-op was kept in. You'll only be able to buddy up over an ad-hoc connection, but that still makes charging through the story mode a lot more fun. The Rumble deathmatch modes made it over as well, and you'll be able to tackle a friend one-on-one or gang-on-gang - although, sadly, these are still two-player only. The good news is that all of the modes run smoothly - other than a slight delay in the sound, we didn't run into problems even with a dozen gang-bangers onscreen.
