The current recommendation is all about the nostalgia ... which should be on this side, no surprise.
A few motivated people are one of THE classic games given new life.
The speech is of course of Turrican. Those who can still remember the dark era of the C64 / Amiga certainly knows this game to do something.
The new edition boasts wonderful pretty Paralax-scrolling, crisp refined images (which remain the original but true), tons of upgrades for the gun, difficult situations, demanding bosses and one full swing of memories during play schonmal abruptly high-spill:)
You have to be quite fast but without a joystick on the keyboard, but this is also the only (minor) drawback of this freeware gem.
So if you still even want to understand the good old days really go in style best shot straight to the page:
