its carp cuz it strings you along pretending its gonna offer you abit more to play through (wheres prophet?! were going back for him!) then it slaps you with a "to be continued"
thats why it sucks!
I also got the 'could not lock on' bug on the final boss so still haven't actually seen the ending
It felt like a 3D Contra near the end sadly.
The ending was weak, though the damage had been done by that stupid 3d floating section. That just annoyed the hell out of me and used up all my ammo. :/
I've also never seen this lock-on bug.
Theres quite a few bugs ive heard of but not actually seen, friend of mine on the final level on the carrier fell through the carrier a few times. ive seen it reported a few times online, also seen a similar bug on warhead where you will fall through one of the final levels.
