Even though it’s SOOOOO low programmed.
I somehow enjoyed it. You just defeat the boss with either a mini gun (Best Preferred) or shotgun (Second-best preferred) and you can extract and win. It’s the red (Flare maybe?) smoke or whatever it is, but yeah! It’s really difficult though, and feels unfair though possible! You don’t gain loot though. So perhaps you can use this game as a training ground game I guess though the HUD feels different from all.
