Far too much lag in the last zone. i have all the upgrades and even got second chance half way through fourth zone but wasnt able to finish because of the lag. i cant do anything except randomly shoot and hope it does something useful by the time it hits. there are too many enemies and the power ups are cr@p i had fun and enjoyed the game in the 1st and 2nd zones but by the 3rd the lag had started to kick in and by the fourth zone it was unbearable. i have tried to get the badge a couple of times since getting all upgrades but have finally given up. 4/5 for the first two zones 1/5 for the last.. overall 2/5
absolutely fantastic game. my first play through was on medium the AI is good once you get used to how it flees you can anticipate it and counter attack. easily... 5/5 it has had me addicted AMAZING
