Well done AI. That's a good screenshot there. I await one of these "Large, outdoor environments" you were talking about previously.
A bit of advice, the script you posted previously is so cliche I chocked on my cup of tea
Alpha team, bravo team, the seemingly emotionless commander who actually really cares for his team, the rookie soldier, it's all too much! Give us something original : D
I wouldn't think soldiers would pause on the field for a debate about who gets to shoot the big sniper rifle while getting hammered by enemy fire. War is a serious matter but in the script it's like they treat it as a game (excuse the pun). All soldiers would have some sniper training. If not then there would be a sniper in their team, unless he's been shot. Even then the most reliable soldier would take up the sniper rifle.
Why is the commander sending a rookie on a solo mission? It's just a cliche, generic scenario. Mix it up a bit man.
Perhaps the commander is shot dead, sending his team into a panic. Getting hit hard with shells most of the team are killed or scattered. The character you play findings himself alone, outside the enemy bunker. As shells rain down all around him his only option is to run inside and carry on the misson alone.

Spartans! Ready your breakfast and eat hearty... For tonight, we dine in Hell!
