How to place C4? Got it, it may be placed only to locked door.
Ahd how to disable C4 in mission 3? Got it, SPACE when blink green, but is blinking so fast!
Summary, pretty good and hardcore stealth-game. I'll be waiting release.
Thanks so much for posting, it helped me find a potentially game-breaking bug! Seems that continuing the campaign after restarting the game causes conversations and some messages to glitch out. It will make getting the best ending impossible. Will have a fix shortly.
Until then, you can edit Player.xml file in Resources/Save folder and change the "currentMission" number at the end of that file to skip ahead to other missions if you get stuck.
