Hello everybody,
Though I dont know if this is something, but anyway let me share this idea with you guys. maybe you already heard about it though.
When you make the clone run in the cave, you know where's its heading for? the alien ship (object. 3). It takes him 50 seconds to get there. If you shoot the alien ship, you will kill the clone president along with the explosion and you'll complete both objectives 3 and 4.
Maybe it saves a couple of seconds compared to not placing the mine, or maybe a new strat can be figured out based on this. I dont know?!
What do ya think about it?
