0 - 1 Minutes Gone

– You’ll start with $30 this time, so place three Gun Towers down in the same central places as before and upgrade them.

1 - 2 Minutes Gone

– Swap out the central Gun Tower for a Flamethrower Tower to maximise your damage output in this key area. – If you hear the sound of a Medic about to arrive, select an item if you have any and when you spot the trail of Fieldrunners, drop your long-lasting item at the start of the pack to take them all out quicker.

2 - 3 Minutes Gone

– Placing a Hive Tower near the top will soften up all units for a faster finish. – Keep using any items you have. Remember: In Time Trial mode, the quicker you dispatch one wave, the quicker the next one starts.

3 - 4 Minutes Gone

– Plant loads of Gun Towers to cover the left entrance so they’re picked off that much quicker. – Stick to this plan for to get those hard-fought three stars.
