You could aslo be ultra Titan Telscope and spam gravity, try improved Titan boombox (idk) the one that is 9k points. It’s actually not bad, every time you do siege you get up to 3k points maybe like 5k. Hope this helps too!
I really like doing upg saw titan the backsaw cuz the damage and cooldown (5 sec) and abnormal range not like the gravity on repair telescope that’s infinite range. go to default map hard or normal endless i like to position myself in front of the last small sandbags front and spam backsaws, and using the hook ability on boxes i cannot reach, i normally destroy the right side building, i reached 52 waves on hard endless 300+ Waves on normal endless since i disconnected. (fun fact - i noticed that when supreme box spawns, they spawn with 505 hp endless mode and when i remember on 50th wave they have like 515 hp since backsaw does 500 damage)
