Space Gun
Space Gun is set in a fictional future, in the year 2039, where humans have begun deep space exploration. From a crippled ship a distress call is transmitted and it is up to the game's protagonist, a special soldier, to respond to the call. When the protagonist boards the ship, they discover it been overrun by hostile and violent alien beings that must be destroyed. The aliens have captured the human crew for an unknown purpose. The story has sections that take place aboard the space craft and on the planet's surface. The protagonist's overall goal is to rescue as many human hostages as possible, eliminate the alien threat and escape the stricken space craft.

Shame
This game is not really good indeed.
The reason is that it is a shamefull Speccy Port.
Just look at the Spectrum version to see what i mean.
The unmasked sprites are a clue, this was used so spectrum wouldn't feature colour clashes...
Ocean was such a great company, yet at the end of the Amstrad Era, they massively ported speccy games instead of doing better stuff, most of them even ended as Vaporware (see Toki).
- But to be fair, the Development for this game was quite erratic.
Supposed to be released as a cartridge game, it was finally rushed to the release probably unfinished as a 6128PLUS disk game.
It uses 128K RAM as launching it on emulator in 64K mode do not work (when coming to game part).
The Coder is the same man who did the quite impressive spectrum version.
But sadly, as he had to change the project from being ROM based to disk based... and as he also probably had no time to finish it completely... the end result is Half promising, half simply not working.
Backgrounds are properly CPC/PLUS coded as the tiles are in 4bpp mode0 and quite well done.
But sprites and animated stuffs are some sort of 1bpp Spectrum graphics (with attributes) transferred into Mode0... probably with a CPU intensive process as the emulation (WinApe, option "find graphics"...) can't enable to find the graphics... (no pre-coded graphix). As a result we can seem ugly attributes and the Wide pixels of Mode0 can't do justice to the design of the varied aliens (on Speccy they manage to look quite good actually)
The use of the Hard-wired sprites is obvious : the target/cross-hair... but sadly the bullets use most of the rest of the HardSprites slots while less or different method could have been used to let some extra Hardsprites slots for extra special effects.
On emulator, the Collision just seem to not work well, on real Hardware this must not be that different.. and the result must be laggy at best.
The playfield also use some raster which are quite similar to the Arcade... but sadly this simply displays even more the unmasked tiles/characters from the sprites. could have been better provided the sprites were properly 4bpp coded as the "raster ink" would be used as a "sort of a mask".
Use of Plus Features
- Plus palette is used throughout (colour fading, extra colours throughout)
- Plus raster line interrupts are used (for changing modes for example)
- Plus screen split is used.
- Plus hardware scrolling is not used.
- Plus DMA sound is not used.
- Plus hardware sprites are used. (used for the title page logo, your aiming reticule, bullets, and the Scanner/Radar at bottom of screen HUD).
The hardware sprites use ink cycling. The Visor uses 2 sprites with some colour cycling and those sprites may change if you change the selected weapon , bullets use 2 sprites slots per frames (6 frames, so 12 slots) and Radar uses 2 Sprites with colour cycles too. Those sprites are all magnified into pseudo Mode0 sized pixels (X=4 and Y=1). To use sprite for the aiming reticule is an easy way to get masked and smooth movement while the game is non masked and attribute movement based.
- Others :
- Mode change : the texts during Menu page or cinematics, and the upper HUD (top of the screen) are in Mode2 (1bpp) while the rest is in mode0 (4bpp). Despite being Mode2, the letters (characters) used 16 pixels and could have been done in mode1. This part seem to slightly bug on emulator.
- multiloadings are used as the game must be quite heavy on memory requirements. on cartridge, this game properly done would have needed 256K or even 512K ROM cartridge. As a result only the 6128 config can play this (with no ROM).
- The cinematic screens look a lot like the C64 version ones but more coloured and with a bit less attributes limitation remains.
- The "find graphics" option on WinApe enables to find the graphics for the 2nd player's HUD... but this multiplayer feature is simply disabled, so just those graphics just became a waste of RAM.
