DESCRIPTION¶
This is a port of Thrust, the classic Commodore 64 game, to un*x and MSDOG.
The object of the game is to lift the
Klystron Pod from the bottom of a
cave and return it safely to space. The
Pod is very heavy (compared to
the ship) and this makes it tougher than it may seem.
You must be careful not to run out of fuel, crash into the cave walls, or let
the enemy artillary outposts shoot you down.
BACKGOUND STORY¶
The resistance is about to launch a major offensive against the Intergalactic
Empire. In preparation for this, they have captured several battle-grade
starships, but they lack the essential power sources for these formidable
craft;
Klystron Pods.
You have been commissioned by resistance to steal these pods from the Empire's
storage planets. Each planet is defended by a battery of
Limpet Guns,
powered by a
Nuclear Power Plant. By firing shots at the power plant,
the guns can be temporarily disabled; the more shots fired at the nuclear
reactor, the longer the guns will take to recharge.
BUT BEWARE!! If you fire too many shots at the reactor, it will become
critical, giving you just ten seconds to clear the plantet before it is
destroyed. If you have not already retrieved the pod stored at the planet,
then you will have failed the mission. If you have retrieved the pod, and you
manage to send the reactor into its critical phase, and leave the planet
safely, you will receive a hefty bonus.
OPTIONS¶
- -h, --help
- Print a usage message and exit with a non-zero status.
- -v, --version
- Print version information on standard output, then
exit.
- -d, --nodemo
- Do not run the demo which is otherwise displayed if the
game is left untouched.
- -e, --nosoundeffects
- If sound is compiled in, be silent anyway.
- -c, --gamma=Value
- Change the brightness of the colors. 1.0 is the default.
Higher values give brighter colors. The value must be positive.
- -j, --jump
- Only draw every third frame. This makes the game a lot
faster.
- -s, --svgamode=MODE
- This option is only applicable to the SVGAlib version of
Thrust.
The format of svgamode is G<width>x<height>x<colors> where
<width>x<height> is at least 320x200 and <colors> has to
be 256. Also, the mode cannot be planar. See the SVGAlib
documentation for details on this. The default is G320x200x256. There has
been success with modes G320x200x256, G640x480x256, G800x600x256 and
G1024x768x256.
- -display display-name
- -geometry geometry-spec
- These options (-display and -geometry) are only applicable
to the X version of Thrust. Se the man page of X for details.
- -m, --noshm
- This option is only applicable to the X version of Thrust.
Do not try to share memory between Thrust and the X server.
- -2, --double
- This option is only applicable to the X version of Thrust.
Double the size of the window. This makes the game slow.
CONTROLS¶
Note that the following keys are the default configuration. This can be changed
by the user by creating a file named .thrustrc in the users home directory.
- A
- Turn counterclockwise
- S
- Turn clockwise
- Enter
- Fire
Shoots a bullet. Different targets have different effect:
The Fuel Tank explodes for 150 points.
The Limpet guns expolde for 750 points.
The Nuclear Power Plant can take a number of hits. When they are
destroyed you are given a short period of time to clear out before the
whole neighbourhood is nuked. If a Power Plant is hit - but not
destoyed - it will recover after a period of time. During this recovery
period, the Limpet guns are not able to fire. 2000 extra points are
scored if the Power Plant is destroyed when the level is finished.
There is exactly one Power Plant in every level.
In the more advanced levels you will find other things to shoot at.
- Right-Ctrl (Right-Shift on MSDOG)
- Thrust
Gives the ship a forward push at the cost of some fuel.
- Spacebar
- Pick up and shield.
If the ship is above a Fuel Tank the ship is refueled, i.e the fuel
is picked up. Two vertical bars are drawn to indicate that fuel is picked
up. When there is no more fuel left in the tank, it disappears and 300
points are scored.
If the ship is close to the Klystron Pod a connecting wire is drawn.
The Pod is picked up when the connecting wire is of the right length. If
spacebar is released before the correct distance is reached the Pod
is not picked up.
When the shield is activated, a circle is drawn around the ship. If the ship
is carrying the Pod, the Pod and the wire are also protected by the
shield. The shield costs fuel to power.
- ESC/Q
- Quit the game
- P
- Pause
- C
- Continue a paused game
