The first new feature one recognize is the HUD. From left to right you can see player health, current-weapon and ammunition.
After the player-spawn you can immediately see the bot, which currently doesn’t have any logic implemented, but the interfaces are there.
The next thing, that the bot gets killed with the Shotgun, Rail-Gun, Rocket-Launcher and Grenade-Launcher.
At last the player hurts him self with a grenade so he can pick up one of the health-packs.
