tr1p tells the story of a guy who had a car accident while driving home from work after a 48h shift. He wakes up at night laying next to his crashed car in a place he doesn't seem to remember as a part of the route he usually takes to go home. Actually... he is now very, very, VERY far from home. This is a Half-Life 2 first person shooter mod. Will you survive and make it back home to your family and friends?
To be fair, you did say it was going to be hard and most of the game is fairly challenging but the first major fight and the last chopper battle are bordering impossible. I finished the game but those two parts are seriously too hard. This is probably because there's no good place to make your stand at while at the same time there's not enough room for the player to fight while on the move and enemies keep spawning all around you.
Another problem was the level design, while mostly ok I spent a lot of time wondering where to go. This wasn't so bad at times (at the first poison zombie) and frustrating at others (after I let the ladder down into the playground). And when you figure out a way that you think is right, you don't know if you're exploiting or just doing what you're supposed to do (e.g. the walk on rail bit in the sewers, after I let the ladder down into the playground etc).
Speaking of exploits there were some bugs. The combines and zombies didn't attack each other except when the headcrab shell hit the playground during the first major fight some combines attacked the headcrabs. This left me wondering if the combines and the zombies are supposed to allies or if its just a bug. And the fast zombies sometimes went through walls when they tried to jump attack me.
The story is virtually nonexistant and what little there is, is just confusing. I mean why is this "normal?" guy wearing a hev-suit? Why does it end at the train, will he be home after that? Why are the combines attacking him, if he's just a worker? Why are the combines cooperating with the zombies, etc? If you're going to have that little story, why can't the protagonist simply be freeman?
Other than that it was fairly entertaining, it could be longer :)
