From Lasse Öörni, creator of the acclaimed Metal Warrior series comes HESSIAN, his most ambitious C64 release yet! Featuring fluid gameplay, immersive movie-style story, detailed character animation, ultra-smooth multi-directional scrolling, a huge science complex to explore, multiple enemies to defeat and guns ... lots of guns!

HESSIAN is also available from Psytronik Software in the following formats:-
Budget C64 disk - presented in a glossy disk sleeve with full colour label. 
Premium+ C64 disk - presented in a clear case with full-colour double-sided inlay.

Collector's Edition - C64 disk version presented in a gorgeous glossy box filled with Hessian goodies including the game soundtrack CD, hypergloss poster, double-sided printed map, badges, keyring, stickers + more!


Take the role of Kim, a low-level security guard at a Throne Group science complex, during the worst night shift of her life!
This involves the Group's inventions spiraling out of control thanks to the megalomaniacal visions of the head scientist Norman Throne, ad-hoc life-saving nanomechanical surgical procedures that grant Kim superior strength and recovery capability, but also the constant dependence on battery power, relentless combat against enemies both robotic and human, and an impending apocalypse!

As a "the c64 mini/maxi" owner you might ask yourself:

Why should I get it if i allready have it? 


Because it is a totally different and much, MUCH better experience! The 2016 version included on "the c64" is much harder to control and can get unfair to the point where you can't get "back in business" by grinding for loot. 

With this version it is still challenging but not impossible. 

The updates that where made to improve the controls result in better aiming, less waste of ammunition (by accidentally shooting to the floor while ducking), better rolling under fire hazards and better hand-to-hand combat (best way to get rid of the ball-like drones at the beginning of the game... Dont waste your ammo!) 

One little, tiny downer is the fact that, at least with my "the c64 mini" and "maxi", the save feature of the cartridge-version does not work. It is no big deal cause you can use the save feature that is integrated in "the c64" or use the disk image, where the save feature works flawlessly! 

Long story short:

Great game, great presentation, great music, great artwork. 


Buy it! 

... Is it just me or does kim look like a partially bald version of ian? Or a bit like hulk hogan? xD nitpicking on one or two pixels cause there is nothing bad to say about this gem!

Wish I had found this before - great game I had not played until yesterday.

This is my tribute...

I just picked this up along with the Metal Warriors games and Steel Ranger. They all look great!

Wow! Great game. I have to try  the other game made by Lasse Öörni.

The Map is missing in the Zip-File.

It should be there now

This is certainly on the retro side of action.

Wow, can you release a demo. I'd love try something like this in an emulator.
