Second level,
One of the main features since the promo footage was environmental opportunities. Click a button on some logging equipment and kill some Jaffa.
This very first instance is bugged. If you click the button, the environmental trap fails to trigger, except from making a noise that the Jaffa investigate. Then your character is locked in position permanently.
I really want to like this game, but these guys have had over a year of delays to get it in a playable state, and one of the difficulty factors is the constant risk of the game being unplayable. Such a shame.
edit:
Looks like it might be all environmental opportunities. This is a problem because it looks like some of them are the intended way to progress in the level. This could actually be game breaking.
