Great game, but I will give you 4/5 due to "blah blah you need to do all missions blah blah". That's just annoying, especially for good and fast players that made it to the final boss without having all 3/4 stats.
Probably one of the worst games on Kongregate.
Matchmaking is broken (I see level 1 guys against level 10+), who's got lowest ping wins, respawn isn't safe (I see loads of spawnkills) and it has too much $ content. Plus, the gamebase is 99% 12 years ranting kids. 1/5 would not play if not badged.
I loved first three. This one could have been a good idea but Holy Christ the jumping on back thing is just meh. 3/5 just for this thing and I hope the next one will be like first three :)
