LEGO CITY Undercover Switch NSP Free Download LEGO City: Undercover, understandably, was considered a big deal by Nintendo when it came to the Wii U exclusively back in early 2013. While it was a welcome arrival, it struggled – like various other titles – to arrest the early slump in system sales, and though Nintendo published the title it was evidently not locked down permanently. One of the few non-licensed LEGO game projects has now arrived on Nintendo Switch, PS4 and Xbox One, with a slightly new look but largely the same content.ROMSLAB.COM BEST SWITCH GAMES

LEGO City is still, of course, a popular brand in ‘real’ LEGO and is well known among kids and big kids alike. As the IP wasn’t tied to a third-party franchise, though, TT Games / TT Fusion had free rein to do as they pleased as long as they incorporated the core ‘real world’ vibe of the brand. When we spoke to the developers at the time it was clear that they’d enjoyed the freedom to produce an amusing game that also took the LEGO series in a bold new direction.

GamePlay

Like pretty much every LEGO game, including the most recent ones, gameplay is simple and also occasionally fiddly. Controls are accessible and mostly fine, but sometimes platforming and the camera can be more awkward that they should be; we’ve made this complaint about most LEGO games, so it’s obviously no different with this re-release. Generally, though, our hero Chase McCain moves pretty well, and it can also be fun experimenting with different vehicles in the game, some that handle beautifully and others like a three-wheeled trolley.

The big change here on Switch, though, is the ditching of dual-screen play – in the original Chase had an in-game tablet that looked awfully similar to the GamePad, and the second screen was a rather charming always-on display. That’s gone, of course, though Chase still has his tablet; in truth the second screen isn’t really missed here. You now use the D-Pad (or the left Joy-Con’s equivalent of it) to answer calls and they pop up on the TV, and there’s a map screen along with ‘scanning’ on the TV. In 2013 much was made of the GamePad as integral to the game, but in practice it’s not a major loss.Asphalt 9: Legends Switch NSP 

Glitches

Let’s cut right to it, though, elements of this port are very sloppy. There are some occasional glitches and hiccups in the visuals, with unexpected oddities at some points – we also had the game crash on us a few times, even after the day one update, and noticed the Switch gets rather hot when running the game docked. That suggests a slightly rushed job.

Interestingly, too, this is one of the first games where we’ve seen a notable performance downgrade in handheld mode. We know from reports in the past that the system has lower processing speeds when undocked and evidently that is a problem here, though we must say the majority of developers have done a far better job of optimisation in other games. The framerate is very choppy when the system is undocked, which is frustrating when there’s also a noticeable visual downgrade. We recommend keeping this one docked and played as a ‘home console’ experience.Blades of Time Switch NSP

Issues

Those performance issues, sadly, indicate a rather low-effort development cycle here, at least at the porting stage. Nice work has been done on the environments and lighting, as mentioned above, but the actual process of running it on Switch at times seems like a ‘plug-in and hope for the best’ approach. In single player when docked the game is quite smooth and pleasing on the eye, with a few occasional choke-points and visual flaws, but playing in handheld mode or co-op simply isn’t good enough.

That’s a shame as, despite the somewhat faded open-world tropes and pop-culture gags that are now a few years out of date, this is an enjoyable, sizeable and worthwhile LEGO experience. After enduring a bit of co-op and portable play for review purposes, we had a far more jolly time playing this on the TV. It’s a humorous and quirky game that embraces the silliness of LEGO, and while its writing is still a tad messy it made us smile plenty of times.Cotton Reboot! Switch XCI
