It's just a project with some difficult gameplay. You must use all of you weapons wisely. If you can handle the situation with the crowbar, use the crowbar. If you cant handle the situation with a crowbar, use another weapon and the crowbar.
Advises:
You can jump over some of the dogs.
You don't need to kill all of your enemies.
Changes:
Now the weapons are: crowbar, hand grenades and 357.
The grunts in the crate area have been replaced with alien grunts.
The 3 maps has been combined into one single map.
If there are still bugs, inform me.
