Up on the roof of a building, Vice will send some men to "teach you a lesson", but your character will do their special attack automatically and kill all the men instantly. The level will then properly start, move right to fight some of the weakest enemies in the game, like Ferris. Smash the barrels in the top right corner to gain a couple of items (usually points bonuses). Defeat all the enemies up here to move inside.

Inside the building, you'll encounter more of the weak enemies, but some new foes will make their first appearance here including knife throwers and charging fatties who can do a lot of damage. There are usually a couple of guns you can use to help you clear this section quickly, such as the shotgun or uzi. After you defeat all the enemies your character will automatically jump out of a window.

After landing from the jump, another fatty enemy will drop down, and another enemy will smash through a door. After taking them out, move right and you'll reach Vice, the boss of this level. He has a dinosaur chained up but he will get it angry and make it attack you.

Take out the raptor first, as he can be annoying with his bite throw. Once the raptor is defeated, he'll revert back to his green skin colour and then run off screen. Vice will still attack though, but he isn't that difficult. He has a flying kick, can use a handgun (he always has one), can jump around the screen quickly and can also call on other enemies to help him fight you; but as long as you avoid his flying kick you should be able to beat him fairly quickly by using your character's combo over and over again.

Defeating the lesser enemies will sometimes get you some extra items, such as grenades or health items. Vice is the easiest boss in the game and he'll make appearances in later levels (in different colors) as a standard enemy.
