Desperate need of help

[GasterSans]

Hello everyone, I'm a new member and I am enrolled in an intermediate level japanese class. And I am having difficulties espressing my sentences in this paper.

For example, for this paper I decided to write about my favourite game which happens to be last of us.

I wanted to talk about what happens to Sara and Joel at the start of the game, but the way I explained it was wrong.
サラとサラのお父さんへいっしょにテクサスを逃げる時、サラのお父さの前にサラはうたれるので、人達がサラとサラのお父さんはゾンピみたいです。
I thought I used the appropriate grammar points but my instructor marked this whole sentence wrong. I don't know what I wrote incorrectly?
I wanted to say that when Sara and her dad were escaping Texas, Sara was shot infront of her father because the people thought they were zombies.

And for this sentence I wanted to express more scenes in the game being hard to bear and of course it was all wrong.
ほかのシーンはやっぱり耐えられません。このゲームは多いシーンが耐えられませんが。

And I wanted to express that there are scenes showcasing cannibalism, corruption, fighting for yourself, saving the world or yourself, and genoicdes.
例えばテーマは人食いとか、だらくとか、彼自身の問うためにを戦うとか、世界のために何が自分の道徳的なにぎもんをする、そしてだいぎゃくさつとかがあります。プレイヤーがひとせいにたとびます。

I really don't know what I am doing wrong...
