Endless mode gets increasingly laggy for no apparent reason as I progress. I'd think it has something to do with things that have already happened not being removed from memory or ended.
I'm currently on Wave 68. It's fun having to pick and choose my upgrades to ensure my dominance, which will inevitably fade. I wish the enemies were more dynamic though. Perhaps they could shoot faster as time goes on, or something like that.
The AI needs to be improved. This is apparent in capture the flag mode especially. Too many times has the person with the flag ran back and forth aimlessly.
yeah, unless you upgrade your tires.
