Well.. To be honest, the game can still be rushed (making it less of a strategical game). Yes,yes, it does take you a bit of experience, but .

Also, the monsters may randomly change. In example, there might be a 1/50 chance (2%) that a blaster soldier will transform into a chick.

If we'd get to play together, I could help you around here .

I suppose starting from hard difficulty would be hard to get in, since this is targeted to be played in a team so hard would give more challenge to the amount of players.

More as a suggestion maybe there could be difficulties option in the regular mode while challenge is locked to hard, so you can play casually or learn the game going tru the easy difficulty.
The problem is that hard has more enemies around the world that you wont see in easier difficulties, so you might not expect them, i think some gunners in the first unit for example.



My exact double handness binds.

Also fun fact, the player model is left handed and the game is default to right hand, so the player shoots from the opposite side than the model. I think there was some engine that flips the playermodel if you use right handness.
