Unfair

This game is really unfair and frustrating for the following reasons

-Enemies run faster than the Sonic
-Enemies rush into your face nonstop
-Enemies kill you way too fast even on the easiest difficulty
-Enemy explosives hit through the walls
-Enemy explosives have a very large hit range
-Enemy snipers shoot you nonstop
-Enemies spawn way too fast and give you no time to react
-The game spawns way too many enemies at once
-The levels don't have enough cover (your head sticks out from most cover anyway)
-The game respawns you way back in the levels
-The game has a useless jump feature
-You can't reload your weapon while sprinting
-Invisible walls you get stuck on
-Metal panels on the floor sticking out and ruining your movement

Other bad things

-Easily forgettable story and characters
-Whole game looks the same
-Bullet sponge boss fights
