In
CaveIn, players assumes the role of a member of the Miner Rescue Team.
They have been called in on a mission to rescue trapped miners in a
dangerous and puzzle-filled 3D environment. The player starts the game
choosing one of two heroes Johnny Red or Parker Blue. Once in the game,
the player views the level from a 3rd person ¾ view camera and
also has the assistance of a mini-map to help get an idea of the overall
state of the game.
The setting is deep within
a collapsing mine with dark shadows and bright toon shaded characters
that boldly contrast each other. Players see camera shakes, crumbling
floors, and debris falling from the ceiling giving the sense that the
cave could collapse any second. Deep dark pits, another danger within
the caves, also are found within the mines and force players to move
with caution.
Traversing the mines room by room, players will undoubtedly encounter
obstacles blocking the path to the next room. One common obstacle is
the rock. The rescue miner can walk into the rock to push it or use
the action button to kick it across the room. Rocks can also be shot,
crushed, blown up, or crumbled. To crumble a rock, get three or more
rocks of the same color together. Crumbling rocks are the most basic
way of clearing a path to exit. Rocks are often found scattered throughout
rooms, but can also fall from the ceiling, or be shot out from the Rockthrower.
Falling rocks can crush miners underneath them if players don't keep
an eye out for the shadow on the floor indicating a rock is about to
drop there. Fast rolling rocks are equally as dangerous if a player
is caught in front of one. Player will need to time their movements
to get out of the path of these or get crushed.

Rock throwers
are machines encountered in the mines that can be very useful for clearing
rocks in a room. These machines launch rocks from which other rocks
can be crumbled. The game mechanics for the rock thrower is very similar
to the classic puzzle game Puzzle Bobble1. Players
may also find other uses for the rock thrower as they progress through
the mines.
The
main objective of the game besides survival is rescuing the trapped
miners lost throughout the caves. The players will find them calling
for help and players need only to touch them to rescue them. Rescued
miners will be tracked within the game and will also give the players
a point bonus to their score. Caution should be used when rescuing miners
as they can be crushed by moving or falling rocks.
A big part of surviving the
mines, is the player escaping to the next room. Sometimes the room is
extremely unstable and about to have a major cave-in. When this can
happen, the player is presented with a timer at the top of the screen.
When this timer expires, rocks fall in rapid succession and will inevitably
crush the miner under a mountain of rock. Once this begins, the only
escape from this fate is the exit and hopefully the player has a clear
path to it.
Lastly,
during the game the player will get help along the way to complete the
rescue mission. Useful items like dynamite, extra chances, and save
points can be found in the mines. These items can be walked over to
be picked up by the player. The dynamite is set by walking over the
yellow placement icon. After setting the dynamite, the player should
get far from the blast. The player will get additional help from the
in-game dialog display at the bottom of the screen. This dialog is used
to present tips, hints, and tell the story. At the beginning of the
game, this dialog sets up the story and give the player a tutorial on
how to play.
