DC Carter: Land Of Hope And Glory mission
When you are escaping the Sol Vita and come down the stairs at the start, on the left hand side there is an explosion which brings down a staircase blocking your way through. However, first kill the men in front of you, then the man on the walkway above the wreckage. Then, instead of having to go through the package room, where you fight Harry for Hammond, go up to the wreckage. There will be a part where the floorway meets the hand rails. If you roll in the correct location, Carter will roll straight through the wreckage, avoiding the package room area and saving time and health.

Health Recovery

Hidden vehicles
You can find some hidden vehicles in the parks of London, such as a sooty van (Little Suzuki van with grass in the back) and a very fun golf cart parked behind huts and bushes around the parks.
Select Free Roam mode once it is unlocked and make your way onto Oxford Street from the start point. Head west past the marble arch and onto Bayswater Road (use the map supplied with the game for road names). Follow Bayswater Road westward as far as the game will allow you to go, then turn left at the blockade onto the Hyde Park Inner Road. The Hyde Park Inner Road U-bends back around to travel through the center of Hyde Park at this point. At the back of this U-bend is an open gate. Go through it, and parked outside a mansion is a Nissan Skyline GTR and a TVR. In the garage opposite the mansion is a Lotus and a go-cart.
To get the Saab 9X concept car and a Triad Gang Car (souped-up Honda) in Free Roam mode, in the mission where Carter infiltrates Jolson's warehouse, go to Chinatown (located in Soho). Go down into the underground garage (the same car park where the Triads and Yardies have a gang war). The position of the cars varies on each floor.
To find a Tank in Free Roam mode, travel east along Birdcage Walk (near Buckingham Palace). There are some open gates on your right about half way along (just after the big white building on the same side). There is a small one-man tank on a plinth just inside the gates. You can shoot from the turret by pressing L3 (horn). It catches cars and people on fire.
To find a Lotus Esprit in Free Roam mode, drive west along Marylebone Road (above where it says Marylebone in red letters on the map). About half way along you will see a green dome on your right. Just after this is a small road on your right, which runs parallel to this road (it has Burger King and Vodafone shops on it). At the end of this small road is a subway entrance. Behind and to the right of this there is an alley next to the HSBC bank. The car is in this alley.
Another Nissan Skyline can be found in an alley behind some boxes in Bermondsey Street, near the Tower Bridge.
To find a Mk II (the car that you start in when you enter Free Roaming mode), can be found in the left hand side of a car park in St. Thomas Street, near the Tower Bridge.
In the "Speakers Corner" of Hyde Park (the corner closest to the Marble Arch) a Golf Cart can be found behind some bushes in an open grassy area. In car park of the building nearby is a Royal Parks gardeners pickup van, with grass and plant cuttings in the back.
To get a modified Peugeot 306, drive west along Horseferry Road (near the Lambeth Bridge). You will see a blue colored alley blocked off with some boxes on your right. Follow the alley and go down into the abandoned multi-story car park. At the bottom is a boy racer Peugeot 306 behind a large container. It has a bodykit, neon lights and a huge sound system in the back.
To get a Ford Transit, find one of the jumps around the city (for example, St. James's Street, near Green Park). There are Ford Transit vans parked in front of them.
