Jurassic Park for the genesis was released in 1993 and offers two different play modes. Either you choose to play as Dr.Grant or you choose to control a Raptor. The gameplay is significantly different between the two.

Grant

Grant has slow movement and take damage from falls. If the distance he falls is too far the game will trigger a Fall To Death Animation (FTDA) sending him to his death.

Difficulty differences

• Easy: Ammo pickups give 15 ammunition. Damage from all sources are low.
• Medium: Ammo pickups give 10 ammunition. Damage from all sources are medium.
• Hard: Ammo pickups give 5 ammunition. Damage from all sources are high (two spike hits takes off a full hp bar)

Tricks

Fall reset

The falling distance can be reset by firing your weapon mid-air thus prolonging the time until the FTDA would trigger. This allow you to survive falls that would otherwise have killed you. NOTE: This does not work for pits which instantly trigger an FTDA such as the bottomless pits in the sewer level.

Fall-to-death cancel

The FTDA can be cancelled by the animation of a ammunitions pickup. This is useful for going down pits where a fall reset is not possible due to the pit causing an instant FTDA. The FTDA is quite short so there aren't many places where there is an ammo pickup close enough. The leftmost pit of the volcano level can be entered by using this trick (as can be seen in the current run).

One more use of this trick is in the Canyon level. Right after the first falling rock segments there is a deep pit. There is an ammunitions pickup right below this pit but the FTDA speeds up the fall when playing so this particular ammunition sprite doesn't have time to load and thus can't be picked up. To counter this, the fall down the pit can be synchronized with the falling of the rocks. The rocks fall at a regular interval and cause huge slowdown. This slowdown makes the FTDA play slow enough for the ammunition sprite to load which will then let you cancel the fall.

Boat Jump

In the river level, it is possible to skip the first T-Rex and a switch of boats. By simply holding forward at the giant waterfall just before the T-rex, it is possible to land unharmed in the river below. This trick depends on how much slowdown the game is currently generating. If the game is suffering from too much slowdown, the boat won't have enough speed and the trick will fail. The slowdown seems to be mostly connected to what animation the T-Rex is currently playing.
