Sentry Gun Program

This is a simulation of the Sentry Gun configuration program as used by Hicks in the film Aliens. It simulates a corridor with Aliens entering at the other end (and sometimes dropping from the roof closer to the gun) and running/crawling towards you. All this in internal to the program (so you have to use your imagination), but it seems to do the job nicely :-)

It is written in AMOS Pro on an Amiga. Click on a picture to view it at full size. If you want to see it running check the info at the bottom of this page to get an AVI file of it.

If you want a copy, just e-mail me (my address is on the main page). I have tried it on UAE (probably the best Amiga emulator for Windows) on my PC and it works okay. Not as good as the real thing, but not bad - so you poor people who don't have an Amiga can have a go :-)

Pictures

You can move the cursor around the screen and select the options (and guns A to D). Some of the options do actually make a difference (choose between auto and manual firing, targetting mode etc.) When you arm it you go to the second screen where the action is.

Here you can shoot by pressing fire (if you selected "Man-Override" or "Semi-Auto" on the first screen), or watch it simulate firing at aliens (if you selected "Auto" or "Semi-Auto" mode).

As it fires, the temperature will increase and the ammo and time will decrease. It starts with 500 rounds and when you get to <=50 rounds the "Critical" warning will flash. Moving, shooting and critical alerts all have sampled sounds from the film.

Here are some pictures of it running on a Windows XP Laptop using the WinUAE Amiga emulator:

Video

If you want to leave a comment on the video, or give it a rating, just click the video when it's playing, and it will take you to the YouTube page (or click here). It's best viewed fullscreen; click the YouTube fullscreen button.

If you want to use it with UAE then I have a config file that will set it up correctly (mostly) and boot the emulated Amiga straight into the program.
NOTE: The Sentry Program instructions are accessed by pressing the Amiga's HELP key. This is mapped to Page Down on the PC keyboard.

You can get WinUAE from here.

Here is my config file for WinUAE 0.9.91 (should work for any later version). You will have to change the directory path setting for your own PC (for the Amiga ROM and Sentry Gun disk file), plus enabling the "filter" setting and stretching the screen to the correct size/ratio is a good idea. Make sure it is running in fullscreen mode, too.
