You need to work on those textures, download LithUnwrap and UVmap them properly to avoid the texture streching like that.
Ok, well I downloaded the singleplayer demo. Unzipped. Loaded the .exe. Had to wait an annoyingly long time for the menu to load (wtf?). Clicked 'New Game', begins loading.
Then *BAM*:
so I click ok...
*BAM*
So I click ok again...
It loads, I walk forward, the hole was hard to notice.I get killed by the guy, expect to be respawned, but no, you make me start a 'new game'. So I expect it this time, I drop down, kill the guy, only to be grenaded by the second guy.
Eff this I'm thinking by now, because it's so damn frustrating. I Ctrl_Alt_Delete, and your little 'Data.exe' process that is running is eating 10% of my CPU. After battling the lag I finally managed to end it.
So yeah, I givethe single player a 1/10, because it's just not playable. Fair enough, it's supposed to be challenging, but that was rediculous. Sorry.
