When you ever fight Venom always remember to dont stay too long near him or spideys spider sense who will you open for an attack. Just punch or kick him 5 times then jump back and wait till you can fight him again. To beat venom the last time, just hit him then jump somewhere safe back. Also remember to not get caught in the fire and don't get hit by wings on the helicopter. Later on the fire will spread acrosss the place and the best tactic to do is to a web swing or climb up a wall and then attack Veno; when you have the chance. Also,remember to dodge his attacks. Because they will cause alot of damage.
