Chiri's Convergence Unlocker tool
I am skipping this section since its MP only and I tend to mainly focus on single player.
-Minor hud issues. Mainly due to 2D hud elements and playing at high convergence can cause some minor annoyances.

Explanation: I haven't played it enough to judge it so I am kind of low balling it. It may be higher, might be a bit lower. Its impossible for me to give an accurate rating when I only played for like 15 minutes before admitting that I wouldn't want to play it since it has no single player support.
