Game Mechanics

Movement on Foot

There is running, where you just press the forward key. Jumping is about 13% faster than running, sprinting is a lot faster. Tap the sprint key repeatedly to sprint faster.

Vehicles

When you enter an occupied car, CJ beats up the occupant. If there's not passenger it's usually faster to get in through the passenger door, because CJ just pushes the driver out. If both seats are occupied it's often faster to shoot the driver.

Leaving the door open

While entering a vehicle, keep JUMP or SPRINT pressed to prevent CJ from closing the door. If you do this when entering a car from the passenger side and push the NPC driver out, the NPC dies.

Getting in through the passenger seat door and leaving it open can be useful when a NPC enters the car after CJ, the NPC can get in instantly.

When getting out of a car, you leave the door open by moving away from it instantly. Open doors don't have collision (CJ just walks through them) but are affected by gravity. If you park the car on a slope or even just partly on a sidewalk, the door swings open/closes accordingly. Open doors also swing when you accelerate/brake.

Leaning on bikes

Tap the lean forward key repeatedly to lean forward on the bike, which makes driving the bike a lot faster. This doesn't work when a passenger is on the bike with you though.

Bustedwarp/Deathwarp

When CJ gets busted or dies he is teleported to the nearest Police Station/Hospital. The idea behind a Bustedwarp/Deathwarp is to use this to reduce travel time. One important factor though is that CJ looses all weapons when doing this, so it is only useful on occasions where this doesn't matter.

Skills

Lung Capacity

CJ trains Lung Capacity when he is underwater, what counts is the time underwater, not the breath that is used. Swimming around underwater drains the breath faster, swimming around on the surface makes it regenerate slower, so this should be avoided if possible.

Weapon Skills

Some weapons have a weapon skill that is increased when you hit something that takes damage. So just shooting in the air or shooting walls doesn't work. There are basicially 3 skill-level: Poor, Gangster and Hitman. Poor starts at skill 0, Hitman is reached at 1000. Gangster is different for different weapons. In between levels there are info displays that tell you to keep practicing to reach the next level.

The following table shows at which number of skill points gangster level is reached, how many points one shot (approximately) increases the level and at what points an info appears:

Weapon	Points per Shot	Gangster	Infos
Pistol	~0.5-1	40	200, 400, 600, 800
Tec9 / Micro-SMG	~0.5	50	200, 400, 600, 800	Tec9 and Micro-SMG share the same skill
M4	2	200	400, 600, 800
AK	3	200	400, 600, 800
Desert Eagle	3	200	400, 600, 800
Shotgun	~4-9	200	400, 600, 800
Combat Shotgun	~3-5	200	400, 600, 800
Sawn-off Shotgun	~3-7	200	400, 600, 800
SMG	1-3	250	400, 600, 800
Silenced Pistol	5	500	200, 400, 600

The numbers are based on the display in the stats menu when you hold a weapon that has a skill level. How much one shot increases the skill is a bit difficult to say, especially with the shotguns, so don't take those numbers too literally.

Frame Limiter / FPS Dependency

On the PC Version there is the Option to disable the Framelimiter (which normally limits the FPS to 25). However in this game the FPS affect many game mechanics, which is why it was agreed on to speedrun on 25-30 fps (anything other than 25 fps needs something like Dxtory or Fraps to limit the FPS).

Higher FPS change a few things, including:

• Driving physics are different, vehicles seem to have more traction
• CJ can sometimes randomly die when climbing things
• Swimming/Diving is a lot slower up to impossible
• You move further while freefalling
• The Sliding Glitch is a lot harder to perform
• Spraying Tags is faster
• Grab detection seems to be fps-dependant, making some hard jumps easier/possible

Harder AI after having been in a car

Getting into a car apparently makes the AI aim better to offset the increased protection the player has. Some missions are a lot harder, because the mission enemies' AI doesn't get reset, even if the mission is on foot.

Missions that are known to cause problems because of this:

• A Home in the Hills gets very difficult if you use a car to drive to the house instead of parachuting/running there.
• Green Goo gets a lot more difficult if you use a car before starting the mission. You can get on the bike near the safehouse before starting the mission to reset the AI.
• Toreno's Last Flight also has a bike in front of it that you can use to reset the AI if you had to drive there in a car.

Glitches

Sliding

Sliding is a form of movement that allows you to move faster than normal running or jumping (but slower than sprinting).

To start the slide, you have to start aiming in the transition between crouching and standing up while moving. So you have to crouch, move, stand up and aim. You can stand up by pressing crouch again or by pressing sprint. Sprint also gives you an extra boost, so that the way to go, so:

Crouch, Move, Sprint, Aim

You have to keep aiming and moving for the slide to keep going. If you stop the slide is interrupted.

Suitable Weapons

Any weapon that slows CJ down while aiming can be used for Sliding. This excludes all melee weapons and explosives because you can't aim them. See the table of sliding speeds for a list of weapons that can be used.

Shooting

You can fire weapons without interrupting the slide, if the weapon can be fired without CJ stopping.

• Weapons that can be fired without stopping: Minigun, Fire Extuingisher, Spraycan, Flame Thrower
• Weapons that can be fired without stopping once you reach Hitman Skill Level: AK47, M4, SMG, Combat Shotgun, Pump-Action Shotgun, Desert Eagle, Silenced Pistol

Speed

The sliding speed depends on how you start the slide as well as the strafe speed of the weapon you slide with, so different weapons have slightly different sliding speeds.

When you aim, CJ slows down to strafe speed. Sliding apparently kind of combines the strafe speed and the speed you have when starting the slide. Starting the slide while not moving means you slide with strafe speed, starting while moving but without using sprint is a bit faster and using sprint when starting the slide is the fastest.

Table of Sliding speeds in comparison to running speed. Note that the percentages might not be exact, even one second timing error can change the percentag by 1-2 percentage points.

Weapon	No Skill	Hitman Level
Running	0%
Jumping	13%
Silenced Pistol	23%	49%
Desert Eagle	23%	51%
Pump-Action Shotgun	25%	45%
SMG	29%	51%
AK-47	18%	33%
M4	18%	33%
Sniper Rifle	23%
Rifle	38%
Flamethrower	25%
Rocket Launcher	22%
Heat-Seaking RL	22%
