The fact that I've played through the demo (which is only the first 30-40 mins of gameplay) four times, and it hasn't played out the same way twice yet, is a testament to the diversity of the gameplay...
I generally use the same tactic (cloak, shoot, cloak, shoot, displace, repeat), but it never goes the same way twice... I love it...

Am I the only one who used a couple of run-throughs to learn to switch off cloaking before firing? Firing, or doing anything else than walking and grabbing, terminates your suit's power completely when you're stealthed... I found out the hard way

Best Regards
