Beat on Hard. This expansion was much better than Blue Shift, and in fact better than the base campaign. It was even more action packed than Blue Shift and the platforming/puzzles not as annoying as Half Life. I liked the new weapons and enemies. Except for the pipe wrench and knife. Why have both? Just makes it more of a pain in the ass to use the weapon swap system. The knife is better but I am not going to press the button an extra time to switch to it. The m249 and sniper rifle were excellent weapons and I found the combat situations too difficult to rely much on the weak smg. I only used the teleport gun once to kill one of those fish monsters; otherwise I used it to go into the other dimension for goodies, especially healing. The spore grenade launcher was awesome, and I made sure to backtrack to keep farming ammo for it. The infinite ammo lightning gun was good for weak enemies and if there is cover to hide behind for recharge. I even used it to shoot down the attack chopper boss. I do wish there were some unique special effects for the new weapons, like if the lightning gun had alternate fire to stun instead of damage, allowing for combos with other weapons (like the freeze gun in Duke 3D).
