I purchased the game via Steam and play it on my not-so-current Phenom II X4 955BE with 8GB RAM and a Geforce GTX970 new. It runs flawlessly on my Full HD TV and two XBox controllers.
It's just fun for two on the couch to hang the puzzles together to solve and eliminate the enemy tactically.
Surely there would still Verbesserungsptential but I know of no other game where you can experience a nice mix of puzzle, a bit of gathering and fighting and to require that all your couple on a screen so without a second computer. The Lego games are not as well implemented as similar but by far.
A pity that there are not more games of this type!
