If Lionel Richie was infatuated with giant mechanical killing machines rather than ladies, he’d be singing an ode to Titanfall right now. Respawn’s shooter is once, twice, three times the UK No. 1 in a row – that’s four times in total if you include its debut week in March.There’s not much else to say about this week’s UK charts; the top ten is made up of the same games from last week, except for Battlefield 4 replacing Trials Fusion. As for Titanfall, it’s dominated most of April and it has the chance to keep that run going in May, at least until the arrivals of Wolfenstein: The New Order, Watch Dogs and Mario Kart 8.
